Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that can work on a mixture of gas fuel or diesel fuel or it could operate on diesel fuel alone. Duel Fuel engines can not work on gas alone since they do not have an ignition system, nor do they have 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.. Like for example, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It could even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain applications which have proved a challenge for the forklift. Like for instance, scrap metal is amongst these problems. To be able to successfully handle things like this requires using the correct 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 Diesel, Gasoline, Battery, Propane and Fuel Cell.
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 popular. The most popular electric power source is the lead-acid battery. Out of internal combustion trucks, around over 90% are propane powered.
The most popular power source for lift trucks is battery. Battery powered models make up approximately 60 percent of the new forklifts sold in the USA. Their benefits include: less maintenance requirements, quiet operation, the ability to be utilized indoors and outdoors with no harmful emissions.
