Lift truck Engines
Forklifts are classified as vehicles with small engines, the same category in which lawnmowers are categorized. The engines of the forklifts all follow the principles of internal combustion. Various lift truck models and brand names would have varying engine design and layout. Forklifts are made more toward producing high torque than for speed. They normally are geared to low speeds. The engine powers the drive wheels of the forklift. The engine is also required to lower and raise the forks via a series of chain pulleys. The majority of forklift engines which are modern are powered by propane since they will be used for indoor applications, where diesel and gasoline engines will be inappropriate because of the exhaust they generate.
Typically, the forklift is a four-cylinder engine-block. Forklift engines are similar to car engines because they hold 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 spring-loaded and one-way.
Engine Function
Propane passes through the opened throttle-plate in a fine spray, once the operator starts up the forklift engine. This fine spray mixes together with air which comes from the mass air intake before moving into the head intake hatches of the cylinder. Every one of the four pistons is staggered to rise in an exact sequence, that compresses the mixture of propane and air as each piston rises to the top of the head. With really exact timing, the battery and alternator of the engine generate an electrical current that passes through the spark plug. The fuel ignites causing an explosion which drives the piston back down to the bottom of the cylinder, leading to a continuous turning of the camshaft. In the cylinder, an air pressure imbalance causes the exhaust to be drawn out through the exhaust hatch when more fuel passes into the cylinder. Propane burns a lot cleaner than gasoline and diesel and the exhaust is not as harmful.
