Containerized Generator Set Layout for Integrated Exhaust Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing generator sets require additional external components and increased space for exhaust systems, leading to higher complexity, shipping costs, and power consumption, especially for High Voltage (HV) systems that need additional low voltage power supplies.
Innovation Solution
A containerized generator set with strategically separated rooms within an ISO standard shipping container, including a cooling room, exhaust room, engine room, and control room, which allows for efficient operation and reduced space requirements by integrating all necessary components within the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If an external exhaust system is coupled to the outside of the housing, then the exhaust gases can be treated, but the space required by the generator set increases
Solution Approach 1:
The exhaust room is merged with the internal housing structure, integrating the aftertreatment system within the container rather than using external components. This combines the exhaust treatment function with the housing structure, reducing the overall space required while maintaining effective exhaust gas treatment capability.
2Temperature
If mechanically driven radiator fans are used in HV generator sets, then cooling can be provided, but power consumption increases and additional LV power supply equipment is required
Solution Approach 1:
The patent replaces mechanically driven radiator fans with electrically driven fans. This substitution eliminates the need for mechanical transmission components and allows the fans to be directly powered by the HV system through power conversion, reducing mechanical complexity and improving power efficiency while maintaining effective cooling capability.
3Use of energy by moving object
If a step down transformer is added to provide LV power for electrically driven fans, then cooling efficiency improves, but system complexity and footprint increase
Solution Approach 1:
The HV power system is designed to serve multiple functions: it powers the generator set, provides cooling through electrically driven fans, and supplies other auxiliary systems. This multi-functional approach eliminates the need for separate LV power supply equipment like step down transformers, reducing system complexity while maintaining efficient cooling operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The containerized design improves generator set operation in restricted volumes, reduces shipping costs, and minimizes additional equipment needs, while also enhancing reliability by using multiple electrical fans and an auxiliary generator for power efficiency.
Implementation Method 1
The cooling room is separated from the exhaust room by the cooling room wall to inhibit heat exchange and air flow between the exhaust room and the cooling room
Implementation Method 2
The exhaust room is separated from the engine room by the exhaust room wall
Implementation Method 3
An air intake system is positioned adjacent the engine room and includes a louver moveable between a retracted position wherein the louver is arranged within the housing, and an extended position wherein the louver extends perpendicular to the first side wall outside the housing

AI summary
Systems and apparatuses include a container for a generator set. The container includes a housing including a cooling room structured to support a radiator and a radiator fan within the housing, an exhaust room structured to support an aftertreatment system, an engine room structured to contain the engine and the alternator within the housing, an air intake system positioned adjacent the engine room, and a control room structured to support control equipment for the generator set. The exhaust room may further support after treatment components including a muffler and an exhaust pipe.
