Lift truck Engines
Forklifts are classified as vehicles with small engines. The engines of the forklift all follow the principles of internal combustion, though the numerous makes and models of forklift will have a different design and layout. Forklifts are made more toward producing 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 required to raise and lower the forks through a series of chain pulleys. The majority of forklift engines which are modern are powered by propane since they would be used for indoor applications, where gasoline and diesel engines will be unsuitable due to the exhaust they produce.
Typically, the forklift is a four-cylinder engine-block. Forklift engines are like automobile engines because they hold pistons connecting to a camshaft. Each and every cylinder head 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 that 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, compressing the propane and air mixture as every piston rises to the top of the head. With really exact timing, the alternator and battery of the engine produce an electrical current that passes through the spark plug. The fuel ignites resulting in 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 as more fuel passes into the cylinder. Propane burns much cleaner than diesel and gasoline and the exhaust is not as harmful.
