Created for longitudinal use in such cars as the Celica and Hilux and in manufacturing from throughuse faded out as numerous of Toyota's mainstream models relocated to front-wheel drive.
This drawing reviews the typical components of a fuel system on a two-stroke engine. Small gas engines serve us in many ways. They power lawn mowers, tillers, cultivators, trimmers, edgers, snowblowers, chain saws, pumps, generators, air compressors, and other useful home tools.
They also power our fun: To keep them operating Engine repair manual, an owner of these tools and toys should know about small engines: Small gas engines are made up of individual systems that work together to produce power. Each system has many components.
Internal combustion gasoline-powered engines require six systems: In this article, we will discuss the systems and components that make small engines work. Fuel and Exhaust The fuel and exhaust systems are critical to operation.
They furnish the fuel for combustion and remove exhaust gases. The following are components of a fuel and exhaust system.
Gasoline is a combustible liquid that burns relatively slowly. However, when sprayed as a mist and mixed with air, it is quite explosive. All it needs is a spark. Two-stroke engines require that oil be mixed with the gasoline to lubricate internal parts.
Four-stroke engines use a fuel-air mixture. The fuel tank stores fuel in preparation for mixing by the carburetor and use by the engine. Some fuel tanks are pressurized with air to help deliver fuel to the carburetor. Other tanks are non-pressurized and depend on a fuel pump to deliver fuel to the carburetor.
Pressurized fuel systems often have a squeeze bulb in the fuel line for building pressure.
A carburetor jet has a small opening that can easily become clogged. A fuel filter traps dirt and sediment from the gas before it is delivered to the carburetor.
A fuel pump produces a vacuum that pulls the fuel from an unpressurized tank, then delivers it to the carburetor.
The carburetor has one job: Too much gasoline in the mixture makes it rich; too little gas makes it lean. The throttle controls the amount of fuel-air mixture that enters the engine from the carburetor. The throttle thus controls the speed of the engine. A primer injects a small amount of gasoline into the carburetor throat to make the initial fuel-air mixture rich.
A primer is used to help start a cold engine. Some engines control the richness of the fuel-air mixture at startup by controlling the air rather than the fuel. A choke reduces the amount of air in the fuel-air mixture.
A governor is a device that automatically opens the engine's throttle when more power is needed and closes it when the load is light. Small gas engines, especially two-stroke engines, are noisy when they operate. A muffler reduces the sound of the exhaust gases by passing them through baffles.
A spark can exit the exhaust port of a small gas engine, potentially starting a fire on nearby combustibles. A spark arrestor on the exhaust port can reduce the chances of such a fire.
Spark arrestors are especially important on chain saws, motorcycles, and all-terrain vehicles operated in dry woodlands.
Ignition The ignition is a primary system within all small gas engines.Nov 24, · The HiFi Engine library has images, specifications and reviews for thousands of audio components, along with free downloads of owners manuals, service manuals, schematics and product catalogues for amplifiers, pre-amps, power amps, tuners, tape decks, cd players etc.
