Dual Fuel Engine
Dual Fuel or DF Engines are the kind of engines that could run on a mixture of diesel fuel and gas fuel or it could operate on diesel fuel alone. Duel Fuel engines can not operate on gas alone because they do not posses an ignition system, nor do they have any spark plugs.
Since diesel is not a pure gas, and it is not a pure diesel designed engine, it has some disadvantages in the department of Methane slippage as well as fuel efficiency.. For example, the fuel efficiency may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It could even be lower or higher loads.
Lift Truck Fuel Sources and Classifications
There are some applications that have proved difficult for the forklift. Like for example, scrap metal is amongst these issues. In order to successfully handle items like this requires utilizing the right kind of machinery for the job.
There are 7 major lift truck classes, including power sources like hydrogen fuel cell, liquid propane gas, gasoline, diesel and electric. The power source is linked to some of these specific classes. The main power sources for forklifts consist of Battery, Diesel, Gasoline, Fuel Cell and Propane.
Electric powered trucks are the most common, mostly Class I, II and class III forklifts. Internal combustion engines are more common in Classes V and IV. The most common electric power source is the lead-acid battery. Amongst internal combustion trucks, roughly more than 90 percent are propane powered.
The most common power source for lift trucks is battery. Battery fueled units make up about 60% of the new forklifts sold within the USA. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be utilized outside and inside with no harmful emissions.
