Forklift Engines
Forklifts are classified as vehicles with small engines, the same category wherein lawnmowers are categorized. The engines of the forklifts all follow the principles of internal combustion. Various forklift models and brand names will have varying engine layout and design. Forklifts are made more toward generating high torque rather than for speed. They normally 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 fueled by propane because they will be utilized for indoor applications, where gasoline and diesel engines would be inappropriate because of the exhaust they produce.
Usually, the lift truck is a four-cylinder engine-block. The engines of the forklift are similar to car engines since they 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 one-way and spring-loaded.
Engine Function
Propane passes through the opened throttle-plate in a fine spray, when the operator starts up the forklift engine. This fine spray mixes together with air coming from the mass air intake before moving into the cylinder's head intake hatches. 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 extremely 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 which 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 exhaust to be drawn out through the exhaust hatch as more fuel passes into the cylinder. Propane burns a lot cleaner than gasoline and diesel and the exhaust is not as harmful.
