Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines which could operate on a mixture of gas fuel or diesel fuel or it can run on diesel fuel alone. Duel Fuel engines could not work on gas alone since they do not have an ignition system, nor do they have any spark plugs.
Because the engine is not a pure diesel engine and diesel is not a pure gas, this machine does suffer from Methane slippage and fuel efficiency. For example, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It can even be greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are some applications that have proved difficult for the forklift. Like for instance, scrap metal is among these problems. In order 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, gasoline, diesel and electric. The power source is linked to several of these particular classes. The main power sources for forklifts include Gasoline, Battery, Diesel, Fuel Cell and Propane.
Electric powered trucks are the most popular, mostly Class I, II and class III forklifts. Internal combustion engines are more common in Classes V and IV. The most common electric power source is the lead-acid battery. Out of internal combustion trucks, approximately over 90% are powered by propane.
The battery is the forklifts most common power source. Battery fueled units make up roughly 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 indoors with no harmful emissions.
