Forklift Engines
Forklifts are classified as small-engine vehicles, the same class in which lawnmowers are classed. Forklift engines all follow the principles of internal combustion. Various 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 usually are geared to low speeds. The engine powers the drive wheels of the forklift. The engine is also needed to raise and lower the forks via a series of chain pulleys. The majority of modern forklift engines are powered by propane as they will be utilized for indoor applications, where gasoline and diesel engines will be inappropriate because of the exhaust they generate.
Normally, the forklift is a four-cylinder engine-block. Forklift engines are similar to automobile engines because they contain pistons connecting to a camshaft. Each and every cylinder head consists of 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, when the operator starts up the engine of the forklift. This fine spray mixes with air which comes from the mass air intake before moving into the head intake hatches of the cylinder. Each and every one of the four pistons is staggered to rise in a precise sequence, compressing the propane and air mixture as each piston rises to the top of the head. With timing that is very precise, the alternator and battery of the engine create an electrical current which passes through the spark plug. The fuel ignites leading to an explosion that 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 than diesel and gasoline and the exhaust is not as harmful.
