Dual Fuel Engine
DF or Duel Fuel Engines are the type 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 could not work 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 Methane slippage and fuel efficiency. Like for example, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It can even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are some applications that have proved difficult for the forklift. For example, scrap metal is among these issues. To be able to successfully handle things like this needs using the right type of equipment for the task.
There are 7 major lift truck classes, including power sources like liquid propane gas, hydrogen fuel cell, electric, gasoline and diesel. The power source is linked to some of these particular classes. The main power sources for forklifts consist of Diesel, Gasoline, Battery, Propane and Fuel Cell.
Electric powered trucks are the most common, mainly Class I, II and class III forklifts. Internal combustion engines are more common in Classes IV and V. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, around more than 90% are powered by propane.
The battery is the forklifts most popular power source. Battery powered models make up approximately 60% of the new forklifts sold within the USA. Their benefits include: quiet operation, less maintenance requirements, the ability to be used outdoors and inside with no harmful emissions.
