Forklift Engines
Forklifts are classified as small-engine vehicles, the same class in which lawnmowers are categorized. Forklift engines all follow the principles of internal combustion. Various lift truck brand names and models would have varying engine design and layout. Forklifts are made more toward producing high torque rather than for speed. They normally are geared to low speeds. The engine powers the drive wheels of the forklift. The engine is also needed to lift and lower the forks via a series of chain pulleys. The majority of forklift engines which are modern are powered by propane since they will be utilized indoors, where gasoline and diesel engines would be inappropriate due to the exhaust they make.
Typically, the forklift is a four-cylinder engine-block. Forklift engines are like car engines as they contain pistons connecting to a camshaft. The head of each and every cylinder consists of an exhaust hatch, a spark plug 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 driver starts up the engine of the forklift. This fine spray mixes with air that comes from the mass air intake prior to moving into the head intake hatches of the cylinder. Each one of the four pistons is staggered to rise in an exact sequence, which compresses the air and propane mixture as every piston rises to the top of the head. With timing that is really precise, the engine's alternator and battery create an electrical current that passes through the spark plug. The fuel ignites leading to an explosion which drives the piston back down to the bottom of the cylinder, resulting in a continuous turning of the camshaft. An air pressure imbalance in the cylinder causes the the exhaust hatch to draw out exhaust as more fuel passes into the cylinder. Propane burns cleaner compared to diesel and gasoline and the exhaust is not as harmful.
