Lift truck Engines
Forklifts are classified as small-engine vehicles, the same category wherein lawnmowers are categorized. Forklift engines 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 generating high torque than for speed. They normally are geared to low speeds. The engine powers the forklift's drive wheels. The engine is also required to lower and lift the forks through a series of chain pulleys. Nearly all forklift engines which are modern are fueled by propane since they will be utilized indoors, where gasoline and diesel engines would be inappropriate due to the exhaust they produce.
A four-cylinder engine-block is usually found in a forklift. Much like the engine in small cars, forklift engines have cylinders containing pistons connecting to a camshaft. The head of each and every cylinder consists of an intake hatch, an exhaust hatch and a spark plug, each of them one-way and spring-loaded.
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 with air that 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, that compresses the propane and air mixture as every 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 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 when more fuel passes into the cylinder. Propane burns cleaner than gasoline and diesel and the exhaust is not as harmful.
