Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines which can run on a mixture of gas fuel or diesel fuel or it could operate on diesel fuel alone. Duel Fuel engines can not work on gas alone since 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 example, the fuel efficiency may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It could even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications which could prove extremely challenging for lift trucks. For example, scrap metal is amongst these issues. In order to successfully handle things like this requires utilizing the correct type of equipment for the task.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, gasoline, diesel and electric. The power source is linked to several of these specific classes. The main power sources for forklifts include Battery, Diesel, Gasoline, Fuel Cell and Propane.
Electric powered trucks are the most popular, mainly Class III, III and class I forklifts. Internal combustion engines are more common in Classes IV and V. The most common electric power source is the lead-acid battery. Among internal combustion trucks, approximately more than 90% are propane powered.
The most popular power source for lift trucks is battery. Battery powered 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 outside and indoors with no harmful emissions.
