Why Use Diesel
Diesel engine generaotrs the best choice for your generator needs for longitivity & efficiency. We guide you why diesel engine generators are better for all generator applications. Why is diesel a better choice for your generator application?

GAS OR DIESEL?  
We recommend diesels due to their: 
a) longevity - think of an 18 wheeler capable of 1,000,000 miles of operation before major service) 
b) lower fuel costs (lower fuel consumption per kilowatt (kW) produced)  
c) lower maintenence costs - no spark system, more rugged and more reliable engine, 
Today’s modern diesels are quiet and normally require less maintenance than comparably sized gas (natural gas or propane) units. Fuel costs per kW produced with diesels is normally thirty to fifty percent less than gas units.  
1800 rpm water cooled diesel units operate on average 12-30,000 hours before major maintenance is required. 1800 rpm water cooled gas units normally operate 6-10,000 hours because they are built on a lighter duty gasoline engine block.  
3600 rpm air-cooled gas units are normally replaced – not overhauled at 500 to 1500 hours.  
Because the gas units burn hotter (higher btu of the fuel) you will see significantly shorter lives than the diesel units. 
How does a diesel work? 
The main differences between the gasoline engine and the diesel engine are:

How does a diesel work? 
The main differences between the gasoline engine and the diesel engine are: 
A gasoline engine intakes a mixture of gas and air, compresses it and ignites the mixture with a spark. A diesel engine takes in just air, compresses it and then injects fuel into the compressed air. The heat of the compressed air lights the fuel spontaneously. 
A gasoline engine compresses at a ratio of 8:1 to 12:1, while a diesel engine compresses at a ratio of 14:1 to as high as 25:1. The higher compression ratio of the diesel engine leads to better efficiency. 
Gasoline engines generally use either carburetion, in which the air and fuel is mixed long before the air enters the cylinder, or port fuel injection, in which the fuel is injected just prior to the intake stroke (outside the cylinder). Diesel engines use direct fuel injection -- the diesel fuel is injected directly into the cylinder. 
The following animation shows the diesel cycle in action. - Click to get a good overview 
Note that the diesel engine has no spark plug, that it intakes air and compresses it, and that it then injects the fuel directly into the combustion chamber (direct injection). It is the heat of the compressed air that lights the fuel in a diesel engine. 
The injector on a diesel engine is its most complex component and has been the subject of a great deal of experimentation -- in any particular engine it may be located in a variety of places. The injector has to be able to withstand the temperature and pressure inside the cylinder and still deliver the fuel in a fine mist. Getting the mist circulated in the cylinder so that it is evenly distributed is also a problem, so some diesel engines employ special induction valves, pre-combustion chambers or other devices to swirl the air in the combustion chamber or otherwise improve the ignition and combustion process.  
One big difference between a diesel engine and a gas engine is in the injection process. Most car engines use port injection or a carburetor rather than direct injection. In a car engine, therefore, all of the fuel is loaded into the cylinder during the intake stroke and then compressed. The compression of the fuel/air mixture limits the compression ratio of the engine -- if it compresses the air too much, the fuel/air mixture spontaneously ignites and causes knocking. A diesel compresses only air, so the compression ratio can be much higher. The higher the compression ratio, the more power is generated.  
Some diesel engines contain a glow plug of some sort (not shown in this figure). When a diesel engine is cold, the compression process may not raise the air to a high enough temperature to ignite the fuel. The glow plug is an electrically heated wire (think of the hot wires you see in a toaster) that helps ignite the fuel when the engine is cold so that the engine can start.  
Smaller engines and engines that do not have such advanced computer controls use glow plugs to solve the cold-starting problem.

We are a team of highly experienced, dedicated and well-trained Engineering Professionals in the field of DG Sets business right from Power Assessment to final commissioning of equipments in a capacity of 5KVA to 2000KVA.

We have a tie up with Diesel Generators sets manufacturers in USA to support our customer base locally and globally for their DG sets requirements and extend the latest technologies in the power generation.  You can see that in our installation and commissioning.  This helps you save money in the long run.

Our services include electrical power assessment, understanding the customer’s requirement and to assist him in selecting appropriate capacity of DG Sets based on their actual need based connected load and electrical power requirement. Further installation and commissioning DG Sets are also undertaken by us.

We have full-fledged independent team of maintenance engineer’s experts in executing Annual Maintenance Contract for the DG Sets for periodical servicing of both on Comprehensive and Non-comprehensive basis.

In recent past Central Board of Pollution Control has come out with notification for emission of Sound Level not exceeding 75db from diesel Generating sets. These critical requirements of noise emission control within a specified limit are mandatory and must be strictly adhered for all DG Set installation. Such customized requirements of Acoustics for DG Sets for also manufactured and commissioned by us.

Besides, DG Sets offered by us Cater the need of DG Set both as captive as well as stand alone upto the capacity of 2000KVA mainly for industries, Process Plants, Information Technology, Petrochemical Industries, Pharmaceutical Industries, Formulation Industries, Core Sectors, Residential Colonies, Hospitals, Theatres, Utilities etc..

We also design and manufacture customized accessories required for DG Sets such as trolley/truck mounted mobile DG Sets, Weather Proof DG Sets, Auto mains failure type control panel etc. based on customer’s requirements.

Thus Bombay Generators offers DG Sets services right from Power assessment, supply, erection and commissioning of equipments at one stop.

Please contact us for further details in respect of your requirement, we shall be pleased to depute our technical representative to see you in person and provide the details thereof.
