Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that can run on a mixture of diesel fuel and gas fuel or it could run on diesel fuel alone. Duel Fuel engines could not work on gas alone because they do not posses 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 Methane slippage as well as fuel efficiency.. For example, the fuel efficiency can be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It can even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain applications that have proved a challenge for the forklift. Like for instance, scrap metal is one of these issues. To be able to successfully handle items like this requires utilizing the correct kind of equipment for the task.
There are 7 major lift truck classes, including power sources like hydrogen fuel cell, liquid propane gas, diesel, electric and gasoline. The power source is linked to some of these specific classes. The main power sources for forklifts include Battery, Diesel, Gasoline, Propane and Fuel Cell.
The most popular overall are electric powered trucks, mostly in Class III, II and class I 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, around more than 90% are propane powered.
The most popular power source for lift trucks is battery. Battery fueled models make up about 60% of the new forklifts sold within the United States. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used outside and indoors with no harmful emissions.
