Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines that could work on a mixture of diesel fuel and gas fuel or it can operate on diesel fuel alone. Duel Fuel engines could not work on gas alone as they do not have an ignition system, nor do they have any spark plugs.
As the engine is not a pure diesel engine and diesel is not a pure gas, this equipment does suffer from Methane slippage and fuel efficiency. For example, the fuel efficiency can be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It can even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are some applications that have proved difficult for the forklift. For example, scrap metal is among these issues. To be able to successfully handle things like this requires utilizing the correct type of machine for the job.
There are 7 major lift truck classes, including power sources like liquid propane gas, hydrogen fuel cell, electric, gasoline and diesel. The power source is linked to some of these particular classes. The main power sources for forklifts comprise Battery, Diesel, Gasoline, Fuel Cell and Propane.
The most common overall are electric powered trucks, mostly in Class I, II and class III forklifts. In Classes V and IV, internal combustion trucks are more common. The most common electric power source is the lead-acid battery. Amongst internal combustion trucks, roughly over 90 percent are fueled by propane.
The most common power source for lift trucks is battery. Battery fueled models make up about 60 percent of the new forklifts sold in the USA. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be utilized outside and indoors with no harmful emissions.
