Dual Fuel Engine
Dual Fuel or DF Engines are the kind of engines that could operate on a mixture of diesel fuel and gas fuel or it could work on diesel fuel alone. Duel Fuel engines could not run on gas alone because they do not have an ignition system, nor do they possess any spark plugs.
Because diesel is not a pure gas, and it is not a pure diesel designed engine, it has some disadvantages in the department of fuel efficiency, as well as Methane slippage.. For instance, 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 lower or higher loads.
Lift Truck Fuel Sources and Classifications
There are certain applications which have proved a challenge for the forklift. Like for instance, scrap metal is among these issues. In order to successfully handle things like this requires using the right kind of machine for the job.
There are 7 major lift truck classes, including 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 comprise Diesel, Gasoline, Battery, Fuel Cell and Propane.
Electric powered trucks are the most common, mostly Class I, II and class III forklifts. Internal combustion engines are more popular in Classes V and IV. The most common electric power source is the lead-acid battery. Amongst internal combustion trucks, approximately more than 90% are fueled by propane.
The most common power source for lift trucks is battery. Battery powered models make up about 60% of the new forklifts sold within the United States. Their benefits consist of: quiet operation, less maintenance requirements, the ability to be utilized inside and outside with no harmful emissions.
