Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines that could work on a mixture of gas fuel or diesel fuel or it can run on diesel fuel alone. Duel Fuel engines can not run on gas alone because they do not have an ignition system, nor do they possess any spark plugs.
As 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 may be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It can even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are certain applications that have proved difficult for the forklift. Like for instance, scrap metal is among these issues. To be able to successfully handle items like this needs utilizing the correct type of equipment for the job.
There are 7 major lift truck classes, including power sources such as 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, Propane and Fuel Cell.
The most popular overall are electric powered trucks, mostly in Class I, II and class III forklifts. In Classes IV and V, internal combustion trucks are more common. The most common electric power source is the lead-acid battery. Among internal combustion trucks, about more than 90 percent are fueled by propane.
The most popular power source for lift trucks is battery. Battery fueled models make up about 60% of the new forklifts sold in the United States. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used indoors and outside with no harmful emissions.
