6 shows the melting behavior ofPLLA/NA samples at heating rate of 10/min aftercooling
process at different cooling rate from melt.
The 6068HFG82 is an extension of the Tier 3 6068HF285 engine that is available today and continues to feature a fixed-geometry turbocharger, high-pressure common-rail fuel system, 2-valve cylinder head, air-to-air aftercooling
and full-authority electronic controls.
5 L inline, four- and six-cylinder engines, all of which feature a four-valve cylinder head, a high-pressure fuel system, turbocharging and an air-to-air aftercooling
Standard N Series high-pressure compressors come complete with motor and starter, as well as aluminum cylinder heads and finned copper cooling pipes for efficient aftercooling
The C15 features electronically controlled unit injection and air-to-air aftercooling
for superior fuel efficiency and reliability.
The 5090B is powered by a Caterpillar (CAT) 3456 diesel engine with air-to-air aftercooling

However, a two-stage turbocharging system integrated with intercooling and aftercooling
allows correct management of the durability-constraining parameters by controlling temperatures throughout the air handling system.
6 liter 3116 incorporates air-to-air aftercooling
, a feature designed to promote fuel economy.
The machine cooling system remains the same for all emissions standards, with no additional heat rejection and no need for engine aftercooling
These engines will feature full-authority electronic controls, a four-valve cylinder head, a high-pressure fuel system, turbo-charging and an air-to-air aftercooling
With a smaller and more robust engine block, the new C32 ACERT engine has a mechanically actuated, electronically controlled unit injection (MEUI) fuel system, Caterpillar's latest ADEM A4 electronic control unit (ECU), plus turbocharging and aftercooling
