Increasingly straight - six engines are also being replaced by turbocharged in - line four cylinder engines that offer comparable top - end power output and reduced low - end torque but with better fuel efficiency, due to smaller displacements and lower friction from
the reduced number of cylinders.
All of the advantages of
a reduced number of cylinders — primarily reduced weight and friction power loss - are being exploited as well.
The technology
reduces the number of cylinders in use to two in light load conditions.
The technology
reduces the number of cylinders in use down to two cylinders in light load conditions.
In the Odyssey and the Accord Hybrid, the active noise - control system counteracts a low - frequency boom caused by the cars» variable - cylinder - management system, which
reduces the number of cylinders in use while cruising.
The 300C Long Wheelbase will have the 5.7 - liter V - 8 HEMIÂ ® engine, generating 340 hp, and the Multi-Displacement System (MDS), which seamlessly
reduces the number of cylinders from eight to four when less power is required, improving fuel economy.
Fuel Saver Technology automatically
reduces the number of cylinders your engine uses when driving conditions permit.

reduced fuel consumption and regulated emissions for a
number of factors, including better high load scavenging for high load performance.
Thanks to new
cylinder - heads with electronic VVT - i valve timing, higher compression (11.8 v 12.3:1), titanium valves, revised intake ports and

The range
of measures here is quite great; for example, engine efficiency can be improved by three different kinds
of measures, increasing thermodynamic efficiency,
reducing frictional losses and
reducing pumping losses (these losses are the energy needed to pump air and fuel into the
cylinders and push out the exhaust) and each kind
of measure can be addressed by a great
number of design, material and technology changes.
