Forklift Engines
Forklifts are classified as vehicles with small engines, the same class wherein lawnmowers are classed. Forklift engines all follow the principles of internal combustion. Various lift truck models and brand names would have varying engine layout and design. Forklifts are made more toward producing high torque than for speed. They generally are geared to low speeds. The engine powers the forklift's drive wheels. The engine is also required to lift and lower the forks via a series of chain pulleys. The majority of modern lift truck engines are fueled by propane since they will be utilized indoors, where gasoline and diesel engines will be inappropriate because of the exhaust they create.
Usually, the lift truck is a four-cylinder engine-block. The engines of the forklift are similar to car engines since they hold pistons connecting to a camshaft. The head of every cylinder consists of an exhaust hatch, a spark plug and an exhaust hatch, each of them one-way and spring-loaded.
Engine Function
Once the operator 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 prior to moving into the head intake hatches of the cylinder. Each and every one of the four pistons is staggered to rise in an exact sequence, that compresses the air and propane mixture as every piston rises to the top of the head. With really precise timing, the battery and alternator of the engine create 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, 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 when more fuel passes into the cylinder. Propane burns a lot cleaner than diesel and gasoline and the exhaust is not as harmful.
