Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines that can operate on a mixture of diesel fuel and gas fuel or it could run on diesel fuel alone. Duel Fuel engines can not run 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 Methane slippage as well as fuel efficiency.. For example, the fuel efficiency can be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It can even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications that can prove very difficult for lift trucks. Like for example, scrap metal is among these problems. To be able to successfully handle items like this requires utilizing the correct kind of machine 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 some of these particular classes. The main power sources for forklifts include Diesel, Gasoline, Battery, Propane and Fuel Cell.
The most common overall are electric powered trucks, mostly in Class III, II and class I forklifts. In Classes V and IV, internal combustion trucks are more common. The most common electric power source is the lead-acid battery. Among internal combustion trucks, around more than 90 percent are fueled by propane.
The most common power source for lift trucks is battery. Battery powered models make up approximately 60 percent of the new forklifts sold in the United States. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be used outside and indoors with no harmful emissions.
