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 run on diesel fuel alone. Duel Fuel engines could not operate on gas alone since they do not posses an ignition system, nor do they possess 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 spark-ignited, lean burn engine at 100 percent load. It can even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are some recycling materials handling applications which can prove really difficult for lift trucks. For example, scrap metal is amongst these issues. To be able to successfully handle things like this needs using the correct kind of machinery for the task.
In this write-up, the 7 major lift truck classes are discussed, including the power sources such as hydrogen fuel cell, liquid propane gas, diesel, electric and gasoline. The power source is linked to several of these specific classes. The main power sources for forklifts include Gasoline, Battery, Diesel, Propane and Fuel Cell.
The most popular overall are electric powered trucks, mostly in Class III, II and class I forklifts. In Classes IV and V, internal combustion trucks are more popular. The most popular electric power source is the lead-acid battery. Amongst internal combustion trucks, about more than 90 percent are fueled by propane.
The most common power source for lift trucks is battery. Battery powered units make up roughly 60% of the new forklifts sold within the United States. Their benefits include: quiet operation, less maintenance requirements, the ability to be used outdoors and inside with no harmful emissions.
