Dual Fuel Engine
DF or Duel Fuel Engines are the type of engines which could operate on a mixture of diesel fuel and gas fuel or it can operate on diesel fuel alone. Duel Fuel engines can not operate on gas alone as they do not have an ignition system, nor do they have any spark plugs.
Since 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.. Like 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 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. Like for example, scrap metal is among these issues. To be able to successfully handle items like this needs using the right kind of machine for the job.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, electric, gasoline and diesel. The power source is linked to some of these particular classes. The main power sources for forklifts consist of Battery, Diesel, Gasoline, Fuel Cell and Propane.
Electric powered trucks are the most common, mostly Class III, III and class I forklifts. Internal combustion engines are more common in Classes IV and V. The most popular electric power source is the lead-acid battery. Amongst internal combustion trucks, about over 90% are propane powered.
The most popular power source for lift trucks is battery. Battery powered units make up approximately 60 percent of the new forklifts sold within the USA. Their benefits include: quiet operation, less maintenance requirements, the ability to be used indoors and outdoors with no harmful emissions.
