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 could work on diesel fuel alone. Duel Fuel engines could not operate on gas alone since they do not have an ignition system, nor do they possess any spark plugs.
Because diesel is not a pure gas, and it is not a pure diesel designed engine, it has some disadvantages in the department of fuel efficiency, as well as Methane slippage.. Like for instance, the fuel efficiency may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It could even be greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are some applications that have proved a challenge for the forklift. For example, scrap metal is one of these problems. To be able to successfully handle items like this needs utilizing the correct type of equipment for the job.
In this write-up, the 7 major lift truck classes are discussed, including the power sources such as liquid propane gas, hydrogen fuel cell, electric, gasoline and diesel. The power source is linked to several of these specific classes. The main power sources for forklifts consist of Diesel, Gasoline, Battery, Propane and Fuel Cell.
The most popular 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 popular electric power source is the lead-acid battery. Amongst internal combustion trucks, approximately over 90% are fueled by propane.
The battery is the forklifts most popular power source. Battery fueled units make up roughly 60% of the new forklifts sold in the USA. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used inside and outside with no harmful emissions.
