  • Small Engine Parts and Operation
    1 Small Engine Parts and Operation INTRODUCTION The small engines used in lawn mowers, garden tractors, chain saws, and other such machines are called internal combustion engines. In an internal combustion engine, fuel is burned inside the engine to produce power. The internal combustion engine produces mechanical energy directly by burning fuel. In contrast, in an external combustion engine, fuel is burned outside the engine. A steam engine and boiler is an example of an external combustion engine. The boiler burns fuel to produce steam, and the steam is used to power the engine. An external combustion engine, therefore, gets its power indirectly from a burning fuel. In this course, you’ll only be learning about small internal combustion engines. A “small engine” is generally defined as an engine that pro- duces less than 25 horsepower. In this study unit, we’ll look at the parts of a small gasoline engine and learn how these parts contribute to overall engine operation. A small engine is a lot simpler in design and function than the larger automobile engine. However, there are still a number of parts and systems that you must know about in order to understand how a small engine works. The most important things to remember are the four stages of engine operation. Memorize these four stages well, and everything else we talk about will fall right into place. Therefore, because the four stages of operation are so important, we’ll start our discussion with a quick review of them. We’ll also talk about the parts of an engine and how they fit into the four stages of operation.

  • Swampʼs Diesel Performance Tips to Help Remove and Install Power
    Injectors-Chips-Clutches-Transmissions-Turbos-Engines-Fuel Systems Swampʼs Diesel Performance Competition Parts For Your Diesel 304-A Sand Hill Rd. La Vergne, TN 37086 Tel 615-793-5573 or (866) 595-8724/ Fax 615-793-5572 Email: [email protected] Tips to help remove and install Power Stroke injectors. Removal: After removing the valve covers and the valve cover gaskets, but before removing any injectors, drain the oil rails by removing the drain plugs inside the valve cover. On 94-97 trucks theyʼre just under where the electrical connectors are on the gasket. These plugs are very tight; give them a sharp blow with a hammer and punch to help break them loose, then use a 1/8" Allen wrench. The oil will drain out into the valve train area and from there into the crankcase. Donʼt drop the plugs down the push rod holes! Also remove one of the plugs on top of each oil rail, (beside where the lines from the High Pressure Oil Pump enter) for a vent to allow air to enter so the oil can drain. The plugs are 5/8”. Inspect the plug O-rings and replace if necessary. If the plugs under the covers leak, it will cause a substantial loss of performance. When removing the injectors, oil and fuel from the passages in the cylinder head drains down through the injector bore into the cylinders. If not removed, this can hydro-lock the engine when cranking. There is a ~40cc dish in the center of each piston. Fluid accumulates in it, as well as in the corner on the outside of the piston between the piston top and the cylinder wall, due to the 45* slope of the cylinder bank.

  • Building on a Heritage of Innovation and Performance
    BUILDING ON A HERITAGE OF INNOVATION AND PERFORMANCE. Over 70 years of the world’s best marine engineering and innovation; a heritage of leading edge technology, performance, fuel economy and advanced reliability; standards that surpass all industry and consumer expectations. Since the beginning in 1939, Mercury Marine has built durable, powerful and innovative small horsepower portable outboard engines. Incorporating innovations throughout the years, including through prop exhaust, first seen on the 1957 Mark-10, Capacitor Discharge Ignition, dual water pickups and Electronic Fuel Injection (EFI), currently available on the 25 and 30hp FourStroke, and that’s only a snapshot. Nobody has a more thorough understanding of Portable outboards and the features they require than Mercury Marine. With 25 models in 66 configurations, ranging from 30hp to 2.5hp Mercury have the right portable option for you. Explore the range of Mercury portables and see why more boaters are starting up a Mercury. Mercury outboards are simply the best, most refined engines money can buy for any marine application. 33 Mercury Innovation Mercury Extreme Reliability Boating is not often thought of as a harsh environment. Just stop and think about it. Marine engines can and are often used for extended periods at wide-open throttle in harsh saltwater and full UV sunlight. Then sit in storage over the off season, in some cases without any use. At Mercury, we test our engines mercilessly and use those results to make them even more reliable. The tougher the test, the tougher the engine. We put our engines through tests such as vicious log strikes, saltwater spray booths, high humidity chambers and hot and cold water temperatures.

  • Digital Twin and Triple Spark Ignition in Four- Stroke Internal Combustion Engines of Two- Wheelers
    International Journal of Innovations in Engineering and Technology (IJIET) Digital Twin and Triple Spark Ignition in Four- Stroke Internal Combustion Engines of Two- Wheelers G.V.N.B.Prabhkar Department Of Mechanical Engineering, V.K.R, V.N.B &A.G.K College of Engineering B.Kiran Babu Department Of Mechanical Engineering, V.K.R, V.N.B &A.G.K College of Engineering K.Durga Prasad Department Of Mechanical Engineering, V.K.R, V.N.B &A.G.K College of Engineering Abstract - Today it is a common trend. It has become a fashion for the people especially living in urban areas to ride such vehicles. Now the companies even want to launch such vehicles that attract the younger generation. This can be achieved by technology known as DTSi. Due to DTSi (digital twin spark ignition) system it is possible to combine strong performance and fuel efficiency. The improved engine efficiency modes have also resulted in lowered fuel consumption. The efficiency of these small engines were enhanced with increased power output just by increasing the number of fuel igniting element i.e. Spark Plug. Spark ignition is one of the most vital systems of an engine. Any variation in the spark timing and number of sparks per minute affects the engine performance severely. Thus a good design and control of the system parameters becomes most essential for optimum performance of an engine. Due to Digital Twin Spark Ignition system it is possible to combine strong performance and higher fuel efficiency. DTSi offers many advantages over conventional mechanical spark ignition system.

  • Small Gasoline Engine Repair, Troubleshooting and Tips
    http://waterheatertimer.org Small Gasoline troubleshooting Engine Repair and Tips Three step approach Determine why a small engine will not start or run properly. Welcome to Find N Choose, your free information site. Fuel - Spark - Compression A gasoline engine needs the following three essentials to "run" In time problems develop with fuel delivery, spark or compression, it only takes one of these to fail to prevent an engine from starting or to run. The first step is to determine which of these is at fault. Three Step Trouble Shooting Spark Place the engine out of bright sunlight, remove the spark plug, reconnect the ignition wire to the spark plug and lie it on the engine head, or metal of the engine, where it makes a path to ground of the engine. Give the rope a tug and observe whether there is a good spark jumping the spark plug electrode gap. A good blue spark is ideal, If there is no spark, try changing the spark plug, and try this test again. No spark indicates ignition problems. 1 of 15 7/25/2011 5:35 PM Small Gasoline Engine Repair, Troubleshooting and Tips http://www3.telus.net/findNchoose/smallenginerepair.html Note the colors and sound to the spark. A fat blue spark that cracks audibly indicates a very good spark. A white spindly sparks indicates a problem in the spark producing mechanism (check grounding of spark coil first) A reddish sparks usually indicate burnt points, or a failing condenser. A weak spark may not ignite the fuel-air under compression. If there is a spark, the problem lies either in fuel delivery, or in the compression of the engine.

  • Technical Information on Considerations When Choosing and Operating a Spark-Plug Sensor Solution
    TECHNICAL INFORMATION ON CONSIDERATIONS WHEN CHOOSING AND OPERATING A SPARK-PLUG SENSOR SOLUTION This paper describes characteristics that must be considered when choosing the correct instrumented spark plugs to substitute for the original standard spark-plugs of an engine in order to allow reliable pressure measurements via the spark-plug bore. Electrode gap The integration of a pressure measurement function requires space inside the spark-plug body. This results in a smaller ceramic insulator for the spark-plug function, and therefore a lower arc-over resistivity. To compensate for the lower arc-over resistivity, the ignition voltage must be low enough to avoid damage to the unit. To reduce the ignition voltage, the Electrode Gap needs to be chosen wisely. This will ensure safe and long lasting operation of the unit. On the other hand, to avoid misfire and therefore insure proper ignition of the air-fuel mixture, the arc of the Electrode Gap requires a minimum length. Choosing this gap will require a tradeoff between a minimum suffi- cient size gap and engine operating condition versus risking an internal arc-over. The maximum Electrode Gap (EG) is determined by the Final Compression Pressure (FCP) from the compression stroke, as this is a convenient metric that is roughly proportional to the demand voltage required to jump the gap in the spark plug. It is neces- sary to match the spark-plug specifications exactly to have reliable firing of the engine and to insure that the demand voltage is not exceeding component limits to avoid permanent damage of the spark-plug sensor assembly.
