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 run on diesel fuel alone. Duel Fuel engines are not able to work on gas alone since 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.. Like for example, the fuel efficiency can be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It can even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are certain applications which have proved difficult for the forklift. Like for instance, scrap metal is one of these problems. In order to successfully handle items like this requires using the right kind of equipment 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 specific classes. The main power sources for forklifts comprise Battery, Diesel, Gasoline, Fuel Cell and Propane.
The most common 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 common electric power source is the lead-acid battery. Amongst internal combustion trucks, about over 90% are propane powered.
The most common power source for lift trucks is battery. Battery powered units make up approximately 60 percent of the new forklifts sold in the USA. Their benefits comprise: less maintenance requirements, quiet operation, the ability to be used indoors and outside with no harmful emissions.
