Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that could operate on a mixture of diesel fuel and gas fuel or it could operate on diesel fuel alone. Duel Fuel engines can not operate on gas alone because they do not posses an ignition system, nor do they have any spark plugs.
Since the engine is not a pure diesel engine and diesel is not a pure gas, this machine does suffer from poor fuel efficiency and Methane slippage. For example, the fuel efficiency can be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It could even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are some applications that have proved a challenge for the forklift. Like for instance, scrap metal is one of these issues. In order to successfully handle items like this requires using the correct type of machine 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 several of these particular classes. The main power sources for forklifts comprise Gasoline, Battery, Diesel, Propane and Fuel Cell.
The most popular overall are electric powered trucks, mostly in Class I, II and class III forklifts. In Classes V and IV, internal combustion trucks are more popular. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, about over 90% are propane powered.
The battery is the forklifts most popular power source. Battery fueled models make up roughly 60 percent of the new forklifts sold within the United States. Their benefits include: quiet operation, less maintenance requirements, the ability to be utilized indoors and outside with no harmful emissions.
