Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines that can run on a mixture of diesel fuel and gas fuel or it could work on diesel fuel alone. Duel Fuel engines can not work on gas alone since they do not have 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 Methane slippage as well as fuel efficiency.. Like for example, the fuel efficiency can be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It can even be greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are certain recycling materials handling applications that could prove very difficult for lift trucks. For instance, scrap metal is one of these problems. In order to successfully handle items like this needs utilizing the right kind of equipment for the job.
There are 7 major lift truck classes, including power sources such as hydrogen fuel cell, liquid propane gas, diesel, electric and gasoline. The power source is linked to some of these specific 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 popular. The most popular electric power source is the lead-acid battery. Among internal combustion trucks, around more than 90 percent are powered by propane.
The battery is the forklifts most popular power source. Battery fueled models make up about 60 percent of the new forklifts sold within the United States. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be utilized outdoors and indoors with no harmful emissions.
