Dual Fuel Engine
Dual Fuel or DF Engines are the kind of engines that can operate on a mixture of gas fuel or diesel fuel or it can work on diesel fuel alone. Duel Fuel engines are not able to operate on gas alone since they do not posses an ignition system, nor do they have any spark plugs.
As 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 may 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 certain applications that have proved difficult for the forklift. Like for instance, scrap metal is among these issues. To be able to successfully handle items like this needs using the correct kind of machine for the job.
In this write-up, the 7 major lift truck classes are discussed, including the power sources such as 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 include Battery, Diesel, Gasoline, Propane and Fuel Cell.
The most popular overall are electric powered trucks, mainly in Class III, II and class I forklifts. In Classes V and IV, internal combustion trucks are more common. The most popular electric power source is the lead-acid battery. Out of internal combustion trucks, around more than 90% are powered by propane.
The battery is the forklifts most popular power source. 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 outdoors and inside with no harmful emissions.
