Forklift Engines
Forklifts are classed as vehicles with small engines. Forklift engines all follow the principles of internal combustion, though the many makes and models of lift truck would have a different layout and design. Forklifts are made more toward generating high torque rather than for speed. They generally are geared to low speeds. The engine powers the drive wheels of the forklift. The engine is also needed to raise and lower the forks through a series of chain pulleys. Most forklift engines that are modern are powered by propane since they would be utilized indoors, where diesel and gasoline engines will be unsuitable due to the exhaust they make.
A four-cylinder engine-block is normally found in a lift truck. A lot like the engine in small automobiles, the engines of the forklift have cylinders which contain pistons connecting to a camshaft. The head of each and every cylinder consists of a spark plug, an intake hatch and an exhaust hatch, each of them one-way and spring-loaded.
Engine Function
Once the driver starts up the engine of the forklift, propane passes through the opened throttle-plate in a fine spray and mixes together with air that comes from the mass air intake before moving into the head intake hatches of the cylinder. Each one of the four pistons is staggered to rise in a precise sequence, which compresses the air and propane mixture as each piston rises to the top of the head. With timing that is really precise, the engine's alternator and battery produce an electrical current which passes through the spark plug. The fuel ignites causing an explosion that drives the piston back down to the bottom of the cylinder, causing a continuous turning of the camshaft. In the cylinder, an air pressure imbalance causes the the exhaust hatch to draw out exhaust when more fuel passes into the cylinder. Propane burns a lot cleaner compared to gasoline and diesel and the exhaust is not as harmful.
