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. -

Stefanowskiego 1/15, 90-924 Lodz, Poland; [email protected] (A.K.); [email protected] (Ł.S.) * Correspondence: [email protected] Abstract: The article is an overview of various materials used in power hydraulics for basic hydraulic actuators components such as cylinders, cylinder caps, pistons, piston rods, glands, and sealing systems. The aim of this review is to systematize the state of the art in the field of materials and surface modification methods used in the production of actuators. The paper discusses the requirements for the elements of actuators and analyzes the existing literature in terms of appearing failures and damages. The most frequently applied materials used in power hydraulics are described, and various surface modifications of the discussed elements, which are aimed at improving the operating parameters of actuators, are presented. The most frequently used materials for actuators elements are iron alloys. However, due to rising ecological requirements, there is a tendency to looking for modern replacements to obtain the same or even better mechanical or tribological parameters. Sealing systems are manufactured mainly from thermoplastic or elastomeric polymers, which are characterized by Citation: Skowro´nska,J.; Kosucki, low friction and ensure the best possible interaction of seals with the cooperating element.

Swampʼs Diesel Performance Tips to Help Remove and Install Power

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. -
Instructions Pro-Stage Ii ™ Throttle Control System
K+R Performance Engineering, Inc. INSTRUCTIONS PRO-STAGE II ä THROTTLE CONTROL SYSTEM Congratulations on your selection of the Pro-Stage II ä Throttle Control System. This top quality unit utilizes twin precision pneumatic actuators for smooth, consistent throttle control, round after round. The use of two actuators allows you to set two different throttle settings, one near idle setting for staging with the Pro-Stage ä system, and another partial throttle setting for down-track E.T. control. Speed controls on the solenoid/valve body assembly give you precise control of throttle opening and closing rates to solve engine stumble and tire spin problems. All components of the system have been carefully selected for corrosion-resistance and long service life with very little maintenance. The Pro-Stage ä system1 is designed to improve driver concentration and reaction time consistency on both Pro and Full (bracket) trees. Control for this system is included in our complete line of Pro-Cubeâ delay box/timer units. BEFORE YOU BEGIN 1. Read all instructions and make sure you understand the operation of the control before you modify your throttle linkage or change any settings or adjustments on the control. 2. Your car MUST have a positive throttle pedal stop such as a bolt or tubular brace fastened to the chassis. Lack of a solid pedal stop could result in consistency problems. 3. SPECIAL NOTE: Factory type throttle cables will NOT work. These cables were not designed for race applications. This system requires a quality after-market “Morse” style cable or solid “rod type” linkage. -

Chevrolet Cars and Trucks Get More with Less by Breathing Right
Chevrolet Cars and Trucks Get More With Less by Breathing Right x Continuously variable valve timing (VVT) available on most Chevrolet models x Four-, six- and eight-cylinder engines continuously adjust air flow for best economy and lowest emissions PONTIAC, Mich. – Athletes understand that proper breathing is critical to maintaining peak performance under all conditions, and so do Chevrolet powertrain engineers. Getting air in and exhaust gases out of the combustion chamber under all speeds and driving conditions are essential to providing outstanding driveability and fuel efficiency with low emissions. “Whether powered by four, six or eight cylinders, virtually every current Chevrolet car and truck – from the compact Cruze to the full-size Suburban – features continuously variable valve timing (VVT) on its engine to optimize its breathing,” said Sam Winegarden, executive director, Global Engine Engineering. With VVT, camshafts are driven by chains from the crankshaft to keep the valve opening in sync with the motion of the pistons in the cylinders. The VVT-equipped Cruze Eco, with EPA-estimated highway fuel economy of 42 mpg, is the most fuel-efficient gasoline-fueled vehicle in America. VVT also contributes to the full-size Silverado XFE’s segment-best 22 mpg highway. Chevrolet’s VVT system uses electro-hydraulic actuators between the drive sprocket and camshaft to twist the cam relative to the crankshaft position. Adjusting the cam phasing in this manner allows the valves that are actuated by that camshaft to be opened and closed earlier or later. On dual overhead cam engines such as the Ecotec inline-four and the 3.6-liter V-6, the intake and exhaust cams can be adjusted independently, allowing the valve overlap (the time that intake and exhaust valves are both open) to be varied as well. -
