Lift truck Engines
Forklifts are classified as small-engine vehicles, the same category in which lawnmowers are categorized. Forklift engines all follow the principles of internal combustion. Different lift truck brand names and models would have varying engine layout and design. Forklifts are made more toward generating high torque than for speed. They usually are geared to low speeds. The engine runs the drive wheels of the forklift. The engine is also needed to lift and lower the forks via a series of chain pulleys. Most modern forklift engines are fueled by propane since they will be used for indoor applications, where diesel and gasoline engines will be unsuitable due to the exhaust they generate.
Typically, the forklift is a four-cylinder engine-block. The engines of the forklift are like automobile engines since they hold pistons connecting to a camshaft. The head of each and every cylinder has an exhaust hatch, a spark plug and an exhaust hatch, each of them one-way and spring-loaded.
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 that comes from the mass air intake prior to moving into the cylinder's head intake hatches. Each one of the four pistons is staggered to rise in a precise sequence, which compresses the mixture of air and propane as each piston rises to the top of the head. With really exact timing, the engine's alternator and battery produce an electrical current that passes through the spark plug. The fuel ignites causing an explosion that drives the piston back down to the bottom of the cylinder, resulting in 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 cleaner than gasoline and diesel and the exhaust is not as harmful.
