Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which can work on a mixture of diesel fuel and gas fuel or it can work on diesel fuel alone. Duel Fuel engines can not operate on gas alone as they do not have 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 fuel efficiency, as well as Methane slippage.. Like for instance, the fuel efficiency can be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It could even be greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are certain applications which have proved a challenge for the forklift. For example, scrap metal is one of these problems. To be able to successfully handle items like this requires utilizing the right kind of machine for the task.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, electric, gasoline and diesel. The power source is linked to some of these specific 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. Among internal combustion trucks, approximately over 90% are propane powered.
The battery is the forklifts most popular power source. Battery fueled models make up roughly 60% of the new forklifts sold in the United States. Their benefits consist of: quiet operation, less maintenance requirements, the ability to be utilized indoors and outdoors with no harmful emissions.
