Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines which could run on a mixture of gas fuel or diesel fuel or it could run on diesel fuel alone. Duel Fuel engines are not able to run on gas alone since 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.. 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 Fuel Sources and Classifications
There are certain applications which have proved a challenge for the forklift. For instance, scrap metal is one of these issues. To be able to successfully handle things like this requires using the correct type of machinery for the task.
In this write-up, the 7 major lift truck classes are discussed, including the 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 I, II and class III forklifts. Internal combustion engines are more popular in Classes IV and V. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, around over 90% are propane powered.
The battery is the forklifts most common power source. Battery fueled units make up around 60% of the new forklifts sold within the USA. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be used outdoors and indoors with no harmful emissions.
