Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines which can operate on a mixture of gas fuel or diesel fuel or it could operate on diesel fuel alone. Duel Fuel engines could not run on gas alone because they do not have an ignition system, nor do they have any spark plugs.
As 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 instance, the fuel efficiency may be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It can even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications which can prove very difficult for lift trucks. For instance, scrap metal is amongst these issues. To be able to successfully handle items like this requires using the correct type of machinery for the job.
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 some of these particular classes. The main power sources for forklifts include Diesel, Gasoline, Battery, Fuel Cell and Propane.
Electric powered trucks are the most common, mainly Class I, II and class III forklifts. Internal combustion engines are more common in Classes IV and V. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, about more than 90 percent are powered by propane.
The most popular power source for lift trucks is battery. Battery fueled models make up about 60 percent of the new forklifts sold in the USA. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be used indoors and outdoors with no harmful emissions.
