Diesel-to-Gas Conversion Kits

Diesel-to-Gas Conversion Kits
Product Detailed
The easiest and the most cost-efficient way to convert diesel engines into CNG/LPG engines.

Special Design and Treatment for Dedicated CNG/LPG Engines:

Engine pistons,valves,valve seats,valve guides,ignition systems,high voltage cables,spark plugs and etc. are especially designed and/or treated CNG/LPG applications with high combusion temperature,high humidity enviroment and over loading.

 

Easy to Convert:

·Replace diesel pistons and related parts to our dedicated CNG/LPG pistons and related components.

·Install our dedicated CNG/LPG cylinder head or drill holes to the original diesel cylinder to put spark plugs.

·Take out the diesel fuel pump and install our distributor or electronic ignition system.

·Install CNG/LPG kit

Notes:

1. Engine model marked * needs new gas cylinder head (the original diesel cylinder head can not be used to drill holes for spark plugs).

More engine models will be available very soon.

Remarks

1

Pistons

Compression ratio (CR) is normally 10.5:1-12:1 for CNG and 9:1-10:1 for LPG. Also shapes of pistons are specially designed for gas engine applications.

Specific CR is determined by engine configuration

2

Valves & valve seats

Special material and special treatment to valves & valve seats for a longer life.

Important for NGV.

3

Cylinder heads

In most of the cases, the diesel cylinder heads can be processed for the installation of spark plugs. However in some other cases, the original diesel cylinder heads can not be processed for the installation of spark plugs, so we need to use the new designed gas cylinder heads.

4

Ignition system

Distributor type ignition system:

Distributor + hi-voltage cables

This is the most cost-efficient way to convert diesel engines into gas

Electronic ignition system (EIS)

Ignition ECU + hi-energy ignition coils + sensors + timing disk + etc.

Higher output KW & torque, lower fuel cost and emission

Remarks

1

Replace old diesel engines by dedicated CNG/LPG engine

CNG or LPG only. MPS supplies dedicated CNG/LPG engines with rated power from 60kw to 170kw (displacement from 2.5 liters to 6.87 liters, engine models include Isuzu 4JA1, 4JB1 and some Chinese gas engines)

Engine pistons, valves, valve seats, ignition systems, high voltage cables, spark plugs and etc. are specially designed and/or treated for CNG/LPG applications with high combustion temperature, high humidity environment and over loading.

2

Replace old diesel engines by petrol-CNG/LPG bi-fuel engine

Driver can choose petrol or gas (CNG/LPG) while driving. MPS supplies 3Y, 4Y, 4Y DOHC 16V, 2RZ bi-fuel engines with rated power 54kw to 100kw.

Customized Development to the New Engine Model:

Basically all the diesel engines can he converted into CNG/LPG. We would like to develop new engine models with our buyers.
