Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which could operate on a mixture of gas fuel or diesel fuel or it can run on diesel fuel alone. Duel Fuel engines could not run 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 equipment does suffer from poor fuel efficiency and Methane slippage. Like for example, the fuel efficiency could be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It could even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are some recycling materials handling applications which can prove extremely difficult for lift trucks. For example, scrap metal is one of these problems. In order to successfully handle items like this needs using the correct type of equipment for the job.
In this write-up, the 7 major lift truck classes are discussed, including the power sources like liquid propane gas, hydrogen fuel cell, 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, 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. Out of internal combustion trucks, approximately more than 90% are powered by propane.
The battery is the forklifts most common power source. Battery fueled models make up approximately 60% of the new forklifts sold in the United States. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be used inside and outdoors with no harmful emissions.
