Dual Fuel Engine
DF or Duel Fuel Engines are the kind 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 operate on gas alone as they do not posses 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 fuel efficiency, as well as Methane slippage.. For instance, the fuel efficiency could be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It can even be greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are some applications that have proved difficult for the forklift. Like for example, scrap metal is amongst these problems. To be able to successfully handle items like this needs utilizing the right kind of equipment for the task.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, gasoline, diesel and electric. The power source is linked to several of these specific 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 III, II and class I forklifts. In Classes IV and V, internal combustion trucks are more popular. The most common electric power source is the lead-acid battery. Out of internal combustion trucks, about over 90 percent are powered by propane.
The battery is the forklifts most popular power source. Battery fueled models make up approximately 60 percent of the new forklifts sold within the USA. Their benefits include: less maintenance requirements, quiet operation, the ability to be utilized indoors and outdoors with no harmful emissions.
