The Power to Do More
Zajac Motors - Platform for Complete Combustion
Other approaches don’t measure up

Zajac Motors has approached engine technology from an entirely new perspective. While others seek to correct the shortcomings of traditional internal combustion Diesel engines by adding “band-aids” and extra boxes to fix increasingly difficult problems, Zajac Motors has chosen to design a more advanced combustion system that simply does not produce the problems in the first place.

Attempts to add “patch” solutions onto 125 year-old Diesel engine designs, often results in degraded fuel economy, increased cost, added complexity, and decreased reliability.  The Zajac Motors approach has none of these undesirable limitations. 

Below is a snapshot that explains why Zajac engine technology is in a league of its own.

The Zajac engine technology is a solution, not a fix.


 

Description

Fuel Efficient

Non-Polluting

Cost Efficient

Light-weight

Quiet Running

Quick Starting

Fuel- Flexibility

DPF
Diesel
Particulate
Filter

Filters soot from exhaust

DOC
Diesel
Oxidation
Catalyst

Completes the “burning” of unburned hydrocarbons in exhaust

EGR
Exhaust
Gas
Recirculation

 Uses oxygen deficient exhaust gas to reduce burn temperature and NOx formation

SCR
Selective
Catalytic
Recirculation

Ammonia injection system to eliminate NOx from exhaust

LSAF
Large
Surface
Area
Filter

LSAF filters take longer to clog and because of their large size, can cause less back pressure

HCCI
Homogenous
Charge
Compression
Ignition

 Controls temperature, pressure, and fuel injection on each compression to try to eliminate flame front and NOx

, Only effective if cylinder has no hot spots or particles

, Low NOx but very high unburned hydrocarbons and carbon monoxide emissions

, Very complex. Requires 15 areas of control

 

     

 

Zajac engine technology

Diesel engine with patented head

, at least 15% more fuel efficient

,, Virtually non-polluting without the use of any costly after-treatments

, Better fuel mileage, less expensive parts to build, no after-treatment operating costs

, through elimination of unneeded parts

, due to clean burn process expanding exhaust gasses to atmospheric pressure before valve opens

, due to efficient engine and flat torque curve variable compression ratio and non-reliance on compression ignition

, runs on any gaseous or liquid fuel
