Dual Fuel Engine
The Dual Fuel engine is a kind of engine which utilizes a mixture of diesel fuel and gas fuel or can run off of diesel by its self. The dual fuel engine is not capable of running on gas alone. These engines do not have ignition systems and do not utilize spark plugs.
As the engine is not a pure diesel engine and diesel is not a pure gas, this machine does suffer from poor fuel efficiency and Methane slippage. Like for example, the fuel efficiency may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100 percent load. It can even be lower or higher loads.
Lift Truck Fuel Sources and Classifications
There are certain applications that have proved a challenge for the forklift. For instance, scrap metal is one of these issues. To be able to successfully handle things like this requires using the right type of machine for the task.
There are 7 major lift truck classes, including power sources such as hydrogen fuel cell, liquid propane gas, electric, gasoline and diesel. The power source is linked to some of these specific classes. The main power sources for forklifts comprise Battery, Diesel, Gasoline, Fuel Cell and Propane.
The most common overall are electric powered trucks, mainly in Class I, II and class III forklifts. In Classes V and IV, internal combustion trucks are more common. The most common electric power source is the lead-acid battery. Amongst internal combustion trucks, approximately more than 90% are fueled by propane.
The battery is the forklifts most common power source. Battery powered units make up approximately 60 percent of the new forklifts sold in the USA. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be used outside and inside with no harmful emissions.
