In a conventional marine diesel engine the power is produced by hot compressed air igniting fuel sprayed under very high pressure into the cylinder head. A marine diesel engine does not use a carburetor to mix fuel and air or spark plugs to ignite the mixture. Instead it employs the pistons to compress the air to 3000 kPa which causes it to become extremely hot and the fuel is ignited as soon as it is injected into the cylinder.
Some marine diesel engines are fitted with a heater plug in the inlet manifold or a glow plug in the pre-combustion chamber of each cylinder to provide additional heat to the combustion air during starting.
Diesel engines are heavier and slower revving than petrol engines but they are also more reliable because they do not rely on external carburetion or an electrical spark for ignition.
Newer engines use an electronic fuel injection system whereby fuel and air are mixed more thoroughly in the pre-combustion chamber before entering the cylinder. This system maximizes power and fuel economy and is also less polluting.
Every boater should have an understanding of how their engine works so let's start by explaining the mechanical cycles.
Most reciprocating piston internal combustion engines work on one of two mechanical cycles-either the four-stroke cycle or the two-stroke cycle. These cycles designate, in correct sequence, the mechanical actions by which the fuel and air gain access to the engine cylinder, the gas pressure - due to combustion - is converted to power and, finally, the burnt gas is expelled from the engine cylinder.
The Basic Four-Stroke Diesel Engine
From its name, it is obvious there are four strokes in one complete engine cycle. A stroke is the movement of the piston through the full length of the cylinder and - since one such movement causes the crankshaft to rotate half a turn - it follows that there are two crankshaft revolutions in one complete engine cycle.
The four strokes in the order they occur are:
1. Inlet stroke. With the inlet valve open and the exhaust valve closed, the piston moves from top dead center (TDC) to bottom dead center (BDC), creating a low-pressure area in the cylinder. Clean, filtered air rushes through the open inlet valve to relieve this low-pressure area, and the cylinder fills with air.
2. Compression stroke. With both valves closed, the piston moves from BDC to TDC, compressing the air. During this stroke the air becomes heated to a temperature sufficiently high to ignite the fuel.
3. Power stroke. At approximately TDC, the fuel is injected, or sprayed, into the hot, compressed air, where it ignites, burns and expands. Both valves remain closed, and the pressure acts on the piston crown, forcing it down the cylinder from TDC to BDC.
4. Exhaust stroke. At approximately BDC the exhaust valve opens and the piston starts to move from BDC to TDC, driving the burnt gas out of the cylinder through the open exhaust valve.
The Two-Stroke Diesel Engine
The two-stroke engine uses two piston strokes to complete one power stroke and, therefore, fire twice as often as a four-stroke engine. A two-stroke engine is smaller and simpler with fewer moving parts. A two-stroke engine has the potential to produce twice as much power as a four-stroke engine of the same size, however, because of the extra fitting required in a two-stroke diesel engine, for example blowers and governors, they become more expensive to produce. There has been a shift towards four stroke diesel engines which have become more efficient and smaller.
Protect Your Marine Diesel Engine
Protect your engine by avoiding long periods (more than 10 minutes) of idling in a "no-load" situation. This is often done to charge batteries or cool refrigeration but if done repeatedly it will glaze the bores of the engine and cause premature engine failure. If the vessel is in a berth the engine can be put in gear to create load at idle.
All boat owners should have an understanding of basic marine diesel engine maintenance to keep themselves and their families safe on the water.
In 1983 when California sprint car racers needed a solution to noise issues at numerous racetracks around America, there were various attempts to try and silence the race cars, and it was discovered that the problem stemmed from the exhaust system. A gentleman by the name of Ray Flugger, with over 26-plus years of exhaust designing experience, was working out of his 800 ft.² barn in Kenwood, California, from where he created flowmaster's first patent design of racing silencers. Flowmaster sounds can be heard on numerous racetracks around America and worldwide today because of his ingenuity and fine ear for sounds and tuned exhaust systems. Ray attached carrying handles to the square-shaped, race mufflers to carry them through the pits, and the mufflers eventually became known as the suitcase muffler. Exhaust systems from this manufacturer started to spring up all over of the racing circuit. Due to their innovation and years of development with top, race-engine builders, motorcycle manufacturers and aftermarket suppliers now marketed these exhaust systems due to the thousands of hours of Dyno research in "real-world" on-track testing.
Vanceandhines exhaust systems is another manufacturer that have been building performance exhaust systems for 25 plus years and their motorcycle exhaust systems are used by many competitors as well. Their high-performance technology is something you may want to consider for your own machine. They pioneered the sport bike exhaust market with the SS2R and the S4 systems. They changed the cruiser market with the 220°, full-coverage, heat-shield technology. This race-inspired, pro-pipe HS continues to set the standard for performance and sound with a 2-into-1-exhaust system! New technologies continue to come into the motorcycle exhaust arena, including proprietary power chamber technologies. This is an amazing equalizer for the traditional 2-into-2-drag pipe, people say all you have to do is twist the throttle and you'll feel the difference.
Borla motorcycle exhaust is another manufacturer that supplies world-class exhaust products that get great customer reviews. They have great manufacturing facilities and are committed to continually improving their standards. They have three US patents for innovative exhaust system technology, and are also worth a serious look. Their stainless-steel motorcycle exhaust system uses mandrel-bent tubing with all-welded construction that is designed for accurate fit and easy installation. They are specialists at merging collector technology and providing the ultimate in power and endurance. They have been at the forefront of the movement toward responsible racing and have a full line of racing mufflers that maintain a race engine's power. In some cases, they have been known to actually add power. Street riders and racers alike have experienced an increase of 7%-10% in horsepower and torque, because of this exhaust system. Whether you're a weekend racer or a professional, you desire nothing but maximum performance. Spend some time online, or visit your local performance shop and learn more about performance exhaust and make a decision for yourself, which one will skyrocket you to first place!

These days, as laser engraving becomes more and more popular, the need for proper ventilation and fume removal is often overlooked. There are three basic methods; direct ventilation out of the building, tapping into a large air handling system, or a stand-alone filtered system. There are advantages and disadvantages to each which will be addressed. It is important to note that most flatbed lasers are operated in a retail environment, relatively small shops or are even home based so not every method of ventilation is applicable.
Laser engraving is very versatile and a wide variety of materials can be processed with attractive results. Because of the diversity of the substrates it is imperative that dust, debris and fumes be efficiently removed from the laser enclosure. The need to ventilate is not unimportant. Considerations include safety, potential damage to the laser and work environment.
Safety for the operator and other personnel in the shop should be paramount for any employer. Lasing is a thermal process and as such the material is burned, melted and vaporized. Some plastics are even toxic when they are heated and the fumes can be harmful when inhaled. To address this all lasers come equipped with a fume removal port that allows external connections.
Air is "pulled" through this port by the vacuum unit and away from the lasing area. What happens to that particle laden air is what differentiates the three ventilation methods.
The simplest method is to use a blower system that draws the air through a hose which is then ported outside the building. This is certainly functional but typically does not handle odor or the fumes very well and often there is a strong residual smell in the work area. In addition, certain parts of the country have EPA (Environmental Protection Agency) rules that prohibit pumping toxic elements into the air. Blower motors tend to operate at a fairly high decibel level so they can be quite loud. The blower motors themselves are inexpensive, but sometimes there are modifications required to the building itself that can drive the overall costs to install up.
In industrial environments there are sometimes existing air handlers that can be tapped into via the laser exhaust port. These very large devices are filtered such that the air they expel in to atmosphere has been "scrubbed" and is not toxic. In most cases they comply with the local EPA restrictions and are totally safe. However these are physically large, expensive units that are designed for use in manufacturing plants and are overkill if purchased solely to operate that standard laser engraving system. If such a system exists in your building by all means explore this as an alternative for your ventilation needs, but make sure that the system has the capacity needed for the laser when venting other equipment in the facility at 100% volume.
The third alternative is a self contained, multi-stage filtered device. As with the others, it attaches to the port on the laser but then draws the air through a series of filters that serve to remove large particles, gasses and odors. The air that is vented from the unit is usually 99% odor free and is safe to inhale. These devices are relatively small, very quiet and are portable. The filters are consumable items and have various operating durations based on usage and the particulate being filtered.
The filter system consists of a large particle filter/or catch bag, a HEPA filter and either an active chemical filter or activated charcoal reservoir. All of the filter elements can be replaced by the user with very little effort. Unlike the other configurations which are hard plumbed to the laser, the stand-alone units are mounted on wheels and can be easily relocated within the shop at the operator's convenience. This makes them the preferred solution for smaller shops and home based businesses.
There are a number of vendors such as Quatro, TBH, Purex and others. If this seems to the best alternative for you take the time to evaluate the systems including the Db level and the consumable costs.
Protecting the laser is also a consideration. Some plastics produce caustic and molten particulate that can infiltrate the moving parts of the laser gantry. In some instances, this can cause rust or non-typical wear on components which can affect the life of the motors, belts, screws and consequently can deteriorate the performance and output of the machine. Out gassing and smoke caused by lasing plastic, wood or coated materials can adhere to the optical components of the unit. Dirty mirrors or lenses lead to low output power or back reflection issues that can result in damage to the system. All adequately sized fume removal systems should have the air volume capabilities to protect the mechanical elements and optical components from these air born particles. All laser manufacturers should be able to provide the CFM requirements for their laser models which can then be used to size the proper exhaust unit.
Having a comfortable work environment is a goal of most shop owners. Managing the odors caused by processing wood, leather, plastics or rubber is part of the effort to keep the employees happy and productive. If you have ever had to smell some of the materials mentioned burning it is obvious how unpleasant it can be. If you take this one step further and consider the customers in the shop you can see how managing the fumes and odors should be a priority. Some vendors operate lasers in malls or other retail locations so courtesy for the storefront next to yours, should not be discounted. The last thing you want to do is to drive your customers out of the shop due to a very manageable situation.
Whether you have already purchased a laser engraver or you are investigating adding one to your shop, do your due diligence when selecting a ventilation method also. The laser is an investment in your business so maximize your return by choosing the proper exhaust system that will extend the life of the machine and provide a safe comfortable working environment for you and your employees.
I'll be happy to provide advice should anyone wish to contact me.

sennheiser px200 headphones luxury wrist watch buy luxury watches brand RV Generator Alert (Why You Should Avoid Home Made Exhaust Systems at All Costs!)RV Generator Alert (Why You Should Avoid Home Made Exhaust Systems at All Costs!)What sparked my interests in the RV Generator issue? Two things actually, the first one was close to home. A good friend of mine, unbeknownst to himself had a carbon monoxide leak slowly seeping into his RV. After installing his rigged up exhaust system, he ran his air conditioning and other appliances off of the portable generator versus off of the RV power. One day as he was driving along, he inexplicably came down with an overwhelming headache and started feeling sick, the cabin felt like it was turning around in circles and he was having trouble thinking clearly. I believe the only thing that saved him was his military training and background. Once those symptoms flared up, he immediately pulled over and got his family out of that death trap on wheels. They had the RV towed to a shop and tests were ran to determine if it was carbon monoxide poisoning or some other issue. When they fired up that generator and let it run, it set off the carbon monoxide detector after twenty minutes. An examination of his homemade system revealed that the integrity of the connector that tied the muffler and the exhaust system together was not properly sealed. Had they let that RV generator run after they had parked, we'd most likely be reading about them on the Channel Five News. Please heed this warning carefully; avoid homemade RV generator exhaust systems at all costs! I have to be honest, being in the generator business, I have seen some pretty dangerous setups jimmy rigged. To this date I have yet to see or identify any homemade installation that meets reasonable standards for safely handling RV generator exhaust gases. Unless you are a mechanical engineer, this is not a do it yourselfer project. The second thing that sparked my interest in addressing this matter is that every year more than a thousand people die in their sleep due to carbon monoxide poisoning. Don't take a chance and become one of them. When these accidents happen due to fumes from a portable generator or some other type of generator, rest assured the incident always finds its way across my desk. Many nights, I have pondered how different the outcome would have been had the person or family been educated on the dangers of carbon monoxide poisoning. There are plenty of options available for those who would like to run their RV generator while parked. If you decide to use one, make sure that the installation is done to specs. Don't allow the person doing the install to cut corners or jimmy rig anything. I've seen people use common couplers and U-clamps to join the muffler from the generator to their exhaust system. A million times NO! I've watched them wrap duct tape around that connection, thinking that would seal it, once again, NO! If you're going to do it, have it done right. Remember, your life and the life of others is at stake. And finally, don't learn this next lesson the hard way. One thing many of these do it yourselfers very rarely take into consideration is the hot pipe their exhaust system exposes others to. All it takes is a child or an unsuspecting adult to touch that piping, and you've got a potential lawsuit on your hands. My suggestion, if you're going to add an exhaust system to your RV generator, get it done professionally if at all possible. If not, use one of the pre-fabbed kits that are recognized by industry experts as being safe. Saturday, October 15, 2011Magnaflow 15738 Stainless Steel Dual Cat-Back Exhaust System
