Thermal overload prediction in large marine engines.
Monitoring and detection of cylinder liner scuffing.
Influence on ambient conditions on engine performance.
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.
Dual fuel CHP facility
Dual fuel CHP facility

Dual fuel CHP facility
Dual fuel CHP facility
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.
Novel engine/refrigeration cycles
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.
Reciprocating Joule cycle concept
Overexpanded engine: utilises energy normally lost to exhaust gases.
Efficiency improvements particularly at low compression ratios.
Can be used to reduce emissions (NOx).
Miller cycle engines
Refrigeration cycles
Expertise in ab/adsorbtion refrigeration cycles.
New cycles / configurations; applications in e.g. fishing vessels.
Free-piston engines
Linear, “crankless” engine.
Simple; compact; low mechanical losses.
Highpressure operation possible: no loadcarrying bearings.
Variable compression ratio.
Modular; flexible engine layout.Further information: www.freepiston.eu
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 cycletocycle variations).
Other ongoing projectsBiofuel microtrigeneration with cryogenic energy storage. UKChina collaboration (Leeds, Ulster, Shanghai Jiaotong, Guangxi, ...).
Funded by EPSRC (£1.1M)

Research project and network funded by EPSRC (>£1M).
Pose2idon: Power Optimised Ship EU FP7 funded; led by BMT Defence Services Ltd.
Life cycle analysis; environmental impact assessment.
