Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that could operate on a mixture of gas fuel or diesel fuel or it could run on diesel fuel alone. Duel Fuel engines could not operate on gas alone as they do not have 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 equipment does suffer from poor fuel efficiency and Methane slippage. Like for instance, 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 Fuel Sources and Classifications
There are some applications that have proved difficult for the forklift. Like for example, scrap metal is one of these issues. In order to successfully handle items like this needs using the correct kind of equipment 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 comprise 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 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, roughly 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 include: quiet operation, less maintenance requirements, the ability to be used outside and indoors with no harmful emissions.
