Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that can operate on a mixture of gas fuel or diesel fuel or it could operate on diesel fuel alone. Duel Fuel engines can not run 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 instance, 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 instance, scrap metal is amongst these issues. To be able to successfully handle things like this requires using the correct type of machinery 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 include Gasoline, Battery, Diesel, Fuel Cell and Propane.
The most common 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 popular electric power source is the lead-acid battery. Amongst internal combustion trucks, around more than 90% are propane powered.
The most common power source for lift trucks is battery. Battery fueled units make up approximately 60 percent of the new forklifts sold in the United States. Their benefits include: less maintenance requirements, quiet operation, the ability to be utilized indoors and outside with no harmful emissions.
