Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that can work on a mixture of diesel fuel and gas fuel or it can work on diesel fuel alone. Duel Fuel engines could not operate on gas alone as they do not have an ignition system, nor do they have 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 lean-burn, spark-ignited engine at 100% load. It could even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain applications which have proved difficult for the forklift. For instance, scrap metal is one of these issues. In order to successfully handle items like this needs using the right kind of machinery 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 several of these particular classes. The main power sources for forklifts comprise Battery, Diesel, Gasoline, Fuel Cell and Propane.
Electric powered trucks are the most common, mainly Class III, III and class I forklifts. Internal combustion engines are more popular in Classes V and IV. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, roughly over 90 percent are propane powered.
The battery is the forklifts most common power source. Battery powered units make up approximately 60% of the new forklifts sold in the United States. Their benefits comprise: less maintenance requirements, quiet operation, the ability to be utilized indoors and outside with no harmful emissions.
