Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines which can run on a mixture of gas fuel or diesel fuel or it can operate on diesel fuel alone. Duel Fuel engines can not operate on gas alone since they do not posses an ignition system, nor do they possess any spark plugs.
As 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. Like for instance, the fuel efficiency could 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 Fuel Sources and Classifications
There are certain applications that have proved difficult for the forklift. Like for example, scrap metal is amongst these problems. In order to successfully handle things like this needs using the correct type of machinery for the task.
There are 7 major lift truck classes, including power sources like hydrogen fuel cell, liquid propane gas, electric, gasoline and diesel. 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 popular. The most common electric power source is the lead-acid battery. Out of internal combustion trucks, about more than 90% are propane powered.
The battery is the forklifts most popular power source. Battery fueled units make up approximately 60% of the new forklifts sold in the United States. Their benefits comprise: less maintenance requirements, quiet operation, the ability to be utilized indoors and outdoors with no harmful emissions.
