Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines which can operate on a mixture of diesel fuel and gas fuel or it can operate on diesel fuel alone. Duel Fuel engines are not able to 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 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 lean-burn, spark-ignited engine at 100 percent load. It can even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications that could prove extremely challenging for lift trucks. For instance, scrap metal is among these problems. To be able to successfully handle things like this needs utilizing the correct kind of machine for the task.
There are 7 major lift truck classes, including power sources such as hydrogen fuel cell, liquid propane gas, gasoline, diesel and electric. The power source is linked to some of these particular classes. The main power sources for forklifts comprise Gasoline, Battery, Diesel, Propane and Fuel Cell.
The most common overall are electric powered trucks, mostly in Class III, II and class I forklifts. In Classes V and IV, internal combustion trucks are more common. The most popular electric power source is the lead-acid battery. Amongst internal combustion trucks, about more than 90 percent are powered by propane.
The battery is the forklifts most common power source. Battery fueled models make up around 60% of the new forklifts sold in the USA. Their benefits consist of: quiet operation, less maintenance requirements, the ability to be utilized inside and outside with no harmful emissions.
