Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines which could work on a mixture of diesel fuel and gas fuel or it could work on diesel fuel alone. Duel Fuel engines can not operate on gas alone since they do not have an ignition system, nor do they have 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 fuel efficiency, as well as Methane slippage.. Like 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 greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are some applications that have proved a challenge for the forklift. Like for example, scrap metal is one of these problems. To be able to successfully handle items like this requires utilizing the correct type of machinery for the job.
In this write-up, the 7 major lift truck classes are discussed, including the power sources like 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 include Gasoline, Battery, Diesel, Propane and Fuel Cell.
The most popular overall are electric powered trucks, mainly in Class III, II and class I forklifts. In Classes IV and V, internal combustion trucks are more common. The most common electric power source is the lead-acid battery. Amongst internal combustion trucks, around more than 90% are propane powered.
The most popular power source for lift trucks is battery. Battery fueled units make up roughly 60 percent of the new forklifts sold within the United States. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used outdoors and inside with no harmful emissions.
