Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that could work on a mixture of gas fuel or diesel fuel or it could work on diesel fuel alone. Duel Fuel engines are not able to operate on gas alone as they do not have an ignition system, nor do they have 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.. For instance, the fuel efficiency can be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It could even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications which could prove very difficult for lift trucks. For instance, scrap metal is amongst these problems. In order to successfully handle things like this requires using the right kind of machine for the task.
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 specific classes. The main power sources for forklifts include Gasoline, Battery, Diesel, Fuel Cell and Propane.
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 popular electric power source is the lead-acid battery. Among internal combustion trucks, about more than 90 percent are fueled by propane.
The most common power source for lift trucks is battery. Battery fueled models make up roughly 60% of the new forklifts sold within the United States. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be utilized indoors and outside with no harmful emissions.
