Dual Fuel Engine
Dual Fuel or DF Engines are the kind of engines which could run on a mixture of gas fuel or diesel fuel or it can operate on diesel fuel alone. Duel Fuel engines can not run on gas alone since they do not posses an ignition system, nor do they possess any spark plugs.
Since the engine is not a pure diesel engine and diesel is not a pure gas, this machinery does suffer from poor fuel efficiency and Methane slippage. Like for example, the fuel efficiency can be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It could even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are some applications which have proved a challenge for the forklift. For example, scrap metal is amongst these problems. To be able to successfully handle items like this requires using the right kind of machinery for the task.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, gasoline, diesel and electric. The power source is linked to some of these specific classes. The main power sources for forklifts include Battery, Diesel, Gasoline, Fuel Cell and Propane.
Electric powered trucks are the most popular, mainly Class I, II and class III forklifts. Internal combustion engines are more popular in Classes V and IV. The most common electric power source is the lead-acid battery. Amongst internal combustion trucks, roughly more than 90% are powered by propane.
The most popular power source for lift trucks is battery. Battery powered models make up approximately 60 percent of the new forklifts sold within the United States. Their benefits comprise: less maintenance requirements, quiet operation, the ability to be utilized outdoors and indoors with no harmful emissions.
