C9.3
Caterpillar
This description highlights the CAT C9.3 ACERT engine, the core power unit that drives the performance of the renowned Cat 336E and 336E H series of large excavators.
This engine is specifically designed and integrated into the Cat 336E series of large excavators, a versatile machine trusted for demanding applications such as mass excavation, heavy construction, quarry operations, and truck loading. The engine's power and efficiency directly support the machine's role in moving high volumes of material.
The C9.3 ACERT engine incorporates advanced technologies to deliver more power with improved fuel efficiency and meet strict emissions standards.
Key technologies include:
ACERT Technology with Advanced Fuel System: This proprietary system uses a high-pressure common rail fuel injection system to optimize combustion, reduce emissions, and provide excellent throttle response. It is also equipped to run on biodiesel fuel blends up to B20.
Intelligent Emissions Management: The engine meets stringent U.S. Tier 4 Interim/EU Stage IV emissions regulations. Its integrated aftertreatment system features an automatic regeneration process that does not interrupt work, along with a manual override option for use in heat-sensitive areas.
Smart Power & Efficiency Controls:
On-Demand Engine Power & Idle Shutdown: The engine automatically adjusts speed based on load and can shut down after a preset idle period to conserve fuel.
Isochronous Speed Control & Power Modes: It maintains a constant speed under varying loads for better fuel economy and offers selectable power modes (High, Standard, Economy) to match job requirements.
Enhanced Performance: Compared to its predecessor in the 336D model, this C9.3 engine delivers up to 12% greater engine power, contributing to the 336E's increased hydraulic lift capacity and overall productivity.
The table below summarizes the main specifications of the C9.3 ACERT engine as used in the 336E excavator.
