Lift truck Engines
Forklifts are classified as small-engine vehicles, the same category in which lawnmowers are categorized. The engines of the forklifts all follow the principles of internal combustion. Different lift truck models and brand names would have varying engine design and layout. Forklifts are designed more toward producing high torque than for speed. They generally are geared to low speeds. The engine runs the forklift's drive wheels. The engine is also required to lower and lift the forks through a series of chain pulleys. The majority of forklift engines that are modern are powered by propane as they will be utilized indoors, where diesel and gasoline engines would be unsuitable because of the exhaust they generate.
A four-cylinder engine-block is usually found in a forklift. A lot like the engine in small cars, the engines of the forklift have cylinders which contain 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 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 cylinder's head intake hatches. Each one of the four pistons is staggered to rise in a precise sequence, compressing the air and propane mixture as every piston rises to the top of the head. With timing which is really precise, the engine's battery and alternator 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 exhaust to be drawn out through the exhaust hatch when more fuel passes into the cylinder. Propane burns cleaner than diesel and gasoline and the exhaust is not as harmful.
