Dual Fuel Engine
Dual Fuel or DF Engines are the kind of engines that can work on a mixture of gas fuel or diesel fuel or it could 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 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 could 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 Classification and Fuel Sources
There are certain recycling materials handling applications which could prove extremely difficult for lift trucks. For example, scrap metal is one of these problems. To be able to successfully handle things like this requires utilizing the right kind of equipment for the task.
In this write-up, the 7 major lift truck classes are discussed, including the power sources such as liquid propane gas, hydrogen fuel cell, electric, gasoline and diesel. The power source is linked to some of these particular classes. The main power sources for forklifts consist of Diesel, Gasoline, Battery, Fuel Cell and Propane.
The most popular overall are electric powered trucks, mainly in Class III, II and class I forklifts. In Classes IV and V, internal combustion trucks are more common. The most popular electric power source is the lead-acid battery. Out of internal combustion trucks, about over 90 percent are propane powered.
The most popular power source for lift trucks is battery. Battery fueled units make up about 60 percent of the new forklifts sold within the USA. Their benefits include: less maintenance requirements, quiet operation, the ability to be used outdoors and inside with no harmful emissions.
