Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that could work on a mixture of gas fuel or diesel fuel or it could run on diesel fuel alone. Duel Fuel engines could not work on gas alone as they do not have 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. For instance, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It could even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications that can prove really challenging for lift trucks. For example, scrap metal is one of these problems. To be able to successfully handle items like this needs using the right kind of machine for the job.
In this write-up, the 7 major lift truck classes are discussed, including the power sources such as hydrogen fuel cell, liquid propane gas, diesel, electric and gasoline. The power source is linked to several of these specific classes. The main power sources for forklifts include Gasoline, Battery, Diesel, Fuel Cell and Propane.
The most popular overall are electric powered trucks, mainly in Class I, II and class III forklifts. In Classes IV and V, internal combustion trucks are more common. The most popular electric power source is the lead-acid battery. Amongst internal combustion trucks, around more than 90% are propane powered.
The battery is the forklifts most popular power source. Battery powered units make up approximately 60% of the new forklifts sold within the USA. Their benefits include: less maintenance requirements, quiet operation, the ability to be utilized inside and outside with no harmful emissions.
