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 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 have any spark plugs.
Since the engine is not a pure diesel engine and diesel is not a pure gas, this machinery does suffer from Methane slippage and fuel efficiency. Like for instance, the fuel efficiency may be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It could even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications that can prove very challenging for lift trucks. For instance, scrap metal is one of these problems. In order to successfully handle items like this needs using the right kind of equipment for the task.
There are 7 major lift truck classes, including power sources such as 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 Gasoline, Battery, Diesel, Fuel Cell and Propane.
Electric powered trucks are the most popular, mostly Class III, III and class I forklifts. Internal combustion engines are more popular in Classes IV and V. The most popular electric power source is the lead-acid battery. Amongst internal combustion trucks, around over 90 percent are powered by propane.
The battery is the forklifts most common power source. Battery powered units make up roughly 60% of the new forklifts sold within the United States. Their benefits comprise: quiet operation, less maintenance requirements, the ability to be utilized outdoors and indoors with no harmful emissions.
