Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines that could run on a mixture of gas fuel or diesel fuel or it can work on diesel fuel alone. Duel Fuel engines could not run on gas alone because they do not posses an ignition system, nor do they have any spark plugs.
Because the engine is not a pure diesel engine and diesel is not a pure gas, this equipment does suffer from Methane slippage and fuel efficiency. For instance, the fuel efficiency may be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It could even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain applications that have proved a challenge for the forklift. For instance, scrap metal is amongst these problems. In order to successfully handle items like this requires utilizing the right kind of machinery for the job.
There are 7 major lift truck classes, including power sources such as hydrogen fuel cell, liquid propane gas, electric, gasoline and diesel. The power source is linked to some of these specific classes. The main power sources for forklifts consist of Gasoline, Battery, Diesel, Propane and Fuel Cell.
The most common overall are electric powered trucks, mainly in Class I, II and class III forklifts. In Classes V and IV, internal combustion trucks are more common. The most common electric power source is the lead-acid battery. Among internal combustion trucks, approximately over 90 percent are propane powered.
The battery is the forklifts most popular power source. Battery fueled units make up approximately 60 percent of the new forklifts sold in the USA. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be utilized outside and inside with no harmful emissions.
