Lift truck Engines
Forklifts are classified as small-engine vehicles, the same class in which lawnmowers are classed. The engines of the forklifts all follow the principles of internal combustion. Various forklift models and brand names would have varying engine layout and design. Forklifts are made more toward producing high torque than for speed. They usually are geared to low speeds. The engine powers the forklift's drive wheels. The engine is also needed to lower and lift the forks via a series of chain pulleys. The majority of modern forklift engines are powered by propane because they would be utilized for indoor applications, where gasoline and diesel engines will be inappropriate because of the exhaust they create.
A four-cylinder engine-block is normally found in a forklift. Much similar to the engine in small automobiles, the engines of the forklift have cylinders that contain pistons connecting to a camshaft. The head of each and every cylinder has a spark plug, an intake hatch and an exhaust hatch, each of them one-way and spring-loaded.
Engine Function
Once the operator starts up the forklift engine, propane passes through the opened throttle-plate in a fine spray and mixes with air which comes from the mass air intake before moving into the cylinder head intake hatches. Each and every one of the four pistons is staggered to rise in an exact sequence, which compresses the mixture of propane and air as each piston rises to the top of the head. With really precise timing, the engine's alternator and battery produce 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, resulting in a continuous turning of the camshaft. An air pressure imbalance in the cylinder causes the the exhaust hatch to draw out exhaust when more fuel passes into the cylinder. Propane burns cleaner compared to gasoline and diesel and the exhaust is not as harmful.
