Forklift Engines
Forklifts are classified as vehicles with small engines, the same category in which lawnmowers are categorized. The engines of the forklifts all follow the principles of internal combustion. Various lift truck models and brand names will have varying engine layout and design. Forklifts are designed more toward generating high torque than for speed. They generally are geared to low speeds. The engine powers the forklift's drive wheels. The engine is also needed to lift and lower the forks through a series of chain pulleys. Most forklift engines which are modern are fueled by propane because they would be used for indoor applications, where diesel and gasoline engines would be inappropriate because of the exhaust they make.
A four-cylinder engine-block is typically found in a lift truck. A lot similar to the engine in small cars, the engines of the forklift have cylinders that contain 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
When the driver starts up the forklift engine, propane passes through the opened throttle-plate in a fine spray and mixes together 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, compressing the mixture of air and propane as every piston rises to the top of the head. With really exact timing, the engine's alternator and battery produce an electrical current that passes through the spark plug. The fuel ignites leading to an explosion that drives the piston back down to the bottom of the cylinder, leading to a continuous turning of the camshaft. An air pressure imbalance in the cylinder 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.
