Dual Fuel Engine
DF or Duel Fuel Engines are the kind of engines that could work 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.
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 example, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It can even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain applications that have proved a challenge for the forklift. Like for instance, scrap metal is one of these issues. In order to successfully handle things like this requires utilizing the right type of machine for the task.
There are 7 major lift truck classes, including power sources like liquid propane gas, hydrogen fuel cell, diesel, electric and gasoline. The power source is linked to several of these specific classes. The main power sources for forklifts comprise 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 popular. The most common electric power source is the lead-acid battery. Out of internal combustion trucks, around more than 90 percent are propane powered.
The battery is the forklifts most popular power source. Battery powered units make up around 60% of the new forklifts sold within the United States. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be used outside and inside with no harmful emissions.
