Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines that can run on a mixture of gas fuel or diesel fuel or it can run on diesel fuel alone. Duel Fuel engines are not able to work on gas alone because they do not have an ignition system, nor do they possess any spark plugs.
Since 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.. Like for instance, the fuel efficiency may 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 Classification and Fuel Sources
There are some applications which have proved a challenge for the forklift. Like for instance, scrap metal is amongst these issues. In order to successfully handle things like this needs utilizing the right type of machine for the job.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, diesel, electric and gasoline. The power source is linked to several of these specific classes. The main power sources for forklifts consist of 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, roughly over 90 percent are fueled by propane.
The battery is the forklifts most common power source. Battery powered models make up approximately 60 percent of the new forklifts sold in the United States. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be used outdoors and inside with no harmful emissions.
