Dual Fuel Engine
Dual Fuel or DF Engines are the kind of engines that could work 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 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.. Like for example, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% 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 instance, scrap metal is among these issues. To be able to successfully handle things like this needs using the right type of machine for the task.
There are 7 major lift truck classes, including power sources like liquid propane gas, hydrogen fuel cell, gasoline, diesel and electric. The power source is linked to some of these particular classes. The main power sources for forklifts comprise Diesel, Gasoline, Battery, Fuel Cell and Propane.
The most common overall are electric powered trucks, mostly in Class I, II and class III forklifts. In Classes IV and V, 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 percent are propane powered.
The battery is the forklifts most common power source. Battery powered units make up around 60% of the new forklifts sold in the USA. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used outdoors and indoors with no harmful emissions.
