Lift truck Engines
Forklifts are classified as vehicles with small engines, the same category wherein lawnmowers are classed. Forklift engines all follow the principles of internal combustion. Various forklift brand names and models will have varying engine layout and design. Forklifts are made more toward generating high torque rather 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 lift and lower the forks via a series of chain pulleys. The majority of forklift engines which are modern are fueled by propane as they will be utilized for indoor applications, where diesel and gasoline engines will be unsuitable due to the exhaust they generate.
A four-cylinder engine-block is typically found in a forklift. A lot like the engine in small automobiles, forklift engines have cylinders which contain pistons connecting to a camshaft. Each and every cylinder head consists of an intake hatch, an exhaust hatch and a spark plug, each of them spring-loaded and one-way.
Engine Function
Propane passes through the opened throttle-plate in a fine spray, when the driver starts up the forklift engine. This fine spray mixes together with air which comes from the mass air intake prior to moving into the head intake hatches of the cylinder. Every one of the four pistons is staggered to rise in an exact sequence, which compresses the propane and air mixture as every piston rises to the top of the head. With timing which is very precise, the battery and alternator of the engine create an electrical current which passes through the spark plug. The fuel ignites resulting in 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 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.
