stage.

4. Engine condition monitoring
 Condition monitoring;
operational optimisation;
emissions control.
 Thermal overload prediction in
large marine engines.
 Monitoring and detection of
cylinder liner scuffing.
 Influence on ambient conditions
on engine performance.

5. Alternative fuels
 Biodiesel and bio­oil engine operation.
 Efficiency and emissions testing.
 Combustion modelling validation.
 Injection properties; viscosity control.
 Small marine craft trials carried out.
 Dual fuel operation: improve combustion
of low­quality fuels by gas injection.
 New experimental facility funded by
Carbon Connections.

6. Dual fuel CHP facility

7. Dual fuel CHP facility

8. Dual fuel CHP facility

9. Dual fuel CHP facility

10. Dual fuel CHP facility

11. Hydrogen-fuelled CI engine
 Low emissions: no CO, CO2, HC; very low NOx.
 Fast combustion: high thermal efficiency.
 Both direct injection and homogeneous charge
compression ignition (HCCI) systems developed
and tested.

12. Novel engine/refrigeration cycles
Reciprocating Joule cycle concept
 Recuperated Joule (gas turbine)
thermodynamic cycle with
reciprocating compressor and
expander.
 Continuous, external combustion
→ low emissions; fuel flexible.
 Efficiency advantages in small scale:
suitable for micro­CHP systems.

13. Refrigeration cycles
 Expertise in ab­/adsorbtion refrigeration cycles.
 New cycles / configurations; applications in e.g. fishing
vessels.
Miller cycle engines
 Over­expanded engine: utilises energy
normally lost to exhaust gases.
 Efficiency improvements particularly at low
compression ratios.
 Can be used to reduce emissions (NOx).

14. Free-piston engines
 Linear, “crankless” engine.
 Simple; compact; low
mechanical losses.
 High­pressure operation
possible: no load­carrying
bearings.
 Variable compression ratio.
Further information:  Modular; flexible engine layout.

15. Free-piston engines
 No crank system → very low frictional losses.
 Lower lubrication requirements; reduced wear.
 Low ignition timing requirements → suitable for HCCI.
 Challenge: piston motion control (load changes and cycle­to­
cycle variations).

16. Other ongoing projects
