Dual Fuel Engine
Dual Fuel or DF Engines are the kind of engines that can work on a mixture of diesel fuel and gas fuel or it could operate on diesel fuel alone. Duel Fuel engines can not work on gas alone since 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 example, the fuel efficiency may be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It can even be greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are certain applications that have proved difficult for the forklift. Like for example, scrap metal is amongst these issues. To be able to successfully handle things like this requires using the correct kind of equipment 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 several of these specific classes. The main power sources for forklifts include Gasoline, Battery, Diesel, Fuel Cell and Propane.
Electric powered trucks are the most popular, mainly Class I, II and class III forklifts. Internal combustion engines are more common in Classes V and IV. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, approximately over 90 percent are fueled by propane.
The battery is the forklifts most common power source. Battery powered models make up approximately 60% of the new forklifts sold in the United States. Their benefits comprise: less maintenance requirements, quiet operation, the ability to be utilized outdoors and indoors with no harmful emissions.
