Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines which could operate on a mixture of gas fuel or diesel fuel or it can operate on diesel fuel alone. Duel Fuel engines could not run on gas alone because they do not posses an ignition system, nor do they possess any spark plugs.
Since 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 instance, the fuel efficiency could be 5% to 8% less than in a comparable spark-ignited, lean burn 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 which could prove extremely challenging for lift trucks. For instance, scrap metal is one of these issues. In order to successfully handle things like this requires utilizing the right type of machinery for the task.
In this write-up, the 7 major lift truck classes are discussed, including the power sources like hydrogen fuel cell, liquid propane gas, diesel, electric and gasoline. The power source is linked to some of these particular classes. The main power sources for forklifts consist of Gasoline, Battery, Diesel, Fuel Cell and Propane.
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. Amongst internal combustion trucks, about over 90% are fueled by propane.
The most common power source for lift trucks is battery. Battery fueled units make up around 60 percent of the new forklifts sold within the United States. Their benefits comprise: less maintenance requirements, quiet operation, the ability to be used indoors and outdoors with no harmful emissions.
