Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines that can work on a mixture of gas fuel or diesel fuel or it can run on diesel fuel alone. Duel Fuel engines can not operate on gas alone because they do not have an ignition system, nor do they possess 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 Methane slippage as well as fuel efficiency.. For instance, the fuel efficiency may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It could even be greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are certain recycling materials handling applications which can prove very difficult for lift trucks. For example, scrap metal is one of these issues. In order to successfully handle things like this needs using the correct kind of equipment for the job.
There are 7 major lift truck classes, including power sources such as hydrogen fuel cell, liquid propane gas, gasoline, diesel and electric. The power source is linked to some of these specific classes. The main power sources for forklifts consist of Diesel, Gasoline, Battery, Fuel Cell and Propane.
The most popular overall are electric powered trucks, mainly in Class III, II and class I forklifts. In Classes IV and V, 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 fueled by propane.
The battery is the forklifts most popular power source. Battery fueled units make up about 60% of the new forklifts sold within the USA. Their benefits consist of: quiet operation, less maintenance requirements, the ability to be utilized indoors and outdoors with no harmful emissions.
