Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which could run on a mixture of diesel fuel and gas fuel or it could operate on diesel fuel alone. Duel Fuel engines are not able to work on gas alone as they do not posses 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 Methane slippage as well as fuel efficiency.. Like for instance, 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 certain applications which have proved a challenge for the forklift. For instance, scrap metal is among these issues. To be able to successfully handle items like this needs using the right type of machine for the job.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, diesel, electric and gasoline. The power source is linked to several of these particular classes. The main power sources for forklifts consist of Gasoline, Battery, Diesel, Fuel Cell and Propane.
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. Out of internal combustion trucks, around more than 90% are propane powered.
The most popular power source for lift trucks is battery. Battery fueled models make up around 60 percent of the new forklifts sold in the United States. Their benefits consist of: quiet operation, less maintenance requirements, the ability to be used inside and outside with no harmful emissions.
