Kawasaki Concours 14 Emissions Control System

The Kawasaki Concours sport touring motorcycle features advanced exhaust and emission control systems to meet environmental regulations while delivering strong performance.

Kawasaki Concours 14 has a catalytic converter, that transforms harmful exhaust pollutants into more benign compounds.

The crankcase emission control system and the Kawasaki Clean Air System help reduce the pollutant levels.

Catalytic Converter

The Concours has a catalytic converter installed in the exhaust system.

This converter uses chemical reactions to convert harmful exhaust pollutants like Hydrocarbons, Carbon Monoxide, and Nitrogen oxides into less harmful compounds like Water Vapor, Carbon Dioxide, and Nitrogen.

Some key points on the catalytic converter:

  • Use only unleaded gasoline to avoid damaging the converter which is designed for unleaded fuel only. Leaded gas will reduce converter effectiveness.
  • Do not operate the bike if the engine misfires. This allows unburned fuel into the converter, overheating it when the engine is hot or reducing performance when cold.

Along with the catalytic converter, the Concours has:

  • A crankcase emission system that routes crankcase vapors back into the engine to be burned instead of releasing them into the air.
  • Evaporative emission controls including low-permeation fuel hoses and fuel tank designs that reduce vapor escape.
  • A secondary air injection system called KCA allows more air into the exhaust so fuel continues burning, reducing hydrocarbons and carbon monoxide.

Crankcase Emission Control System

The crankcase emission control system ingeniously eliminates the release of crankcase vapors into the atmosphere.

Instead, these vapors embark on a journey through an oil separator to the intake side of the engine.

During the engine’s operation, these vapors are drawn into the combustion chamber, where a dance of fuel, air, and combustion magic occurs.

Exhaust Emission Control System

The Exhaust Emission Control System emerges as a critical player in minimizing the environmental footprint of the motorcycle.

The fuel, ignition, and exhaust systems are not mere components; they are a harmonious composition designed for an efficient engine with impressively low exhaust pollutant levels.

What’s more, the exhaust system proudly boasts a catalytic converter, the unsung hero in the battle against harmful emissions.

Evaporative Emission Control System

Kawasaki’s commitment to environmental stewardship extends to the Evaporative Emission Control System.

This system, in compliance with stringent regulations, consists of low-permeation fuel hoses and a fuel tank.

For the California model, it goes a step further, ensuring that fuel vapors resulting from evaporation are not recklessly vented into the atmosphere.

Instead, they embark on a purposeful journey – either being burned in the running engine or stored safely in a canister during engine downtime.

Kawasaki Clean Air System (KCA)

Enter the Kawasaki Clean Air System (KCA), a technological marvel that transforms spent fuel charges into an environmental ally.

As hot fuel charges find their way into the exhaust system, the KCA System intervenes, introducing extra air for continued combustion.

This not only burns up normally unburned gases but also orchestrates the conversion of a substantial portion of carbon monoxide into the more benign carbon dioxide.

Air Suction Valves

The Air Suction Valves play a crucial role in maintaining engine health.

These check valves permit fresh air flow from the air cleaner into the exhaust port while preventing any return.

Periodic inspections are vital for stable idling and performance.

However, it’s imperative to highlight that removal and inspection should be entrusted only to competent mechanics, as detailed in the Service Manual.

Air Cleaner Maintenance

Closing our exploration is the vital topic of Air Cleaner Maintenance.

A clogged air cleaner, akin to a respiratory ailment for the engine, can lead to increased fuel consumption, reduced power, and spark plug fouling.

Kawasaki emphasizes the importance of timely air cleaner replacement, especially in challenging conditions.

Stray away from risks – use only the recommended air cleaner element (Kawasaki part number 11013-0014) to safeguard engine longevity and performance.

Tampering with the Noise Control System Prohibited

Federal law sternly warns against tampering with the Noise Control System.

From muffler replacements to modifications in the air intake system, any interference is considered a breach.

This section serves as a reminder that the roar of a motorcycle should be harmonious with environmental responsibility.

Environmental Impact

The Kawasaki Concours 14 stands as a testament to the motorcycle industry’s commitment to reducing environmental impact without compromising performance.

Central to this endeavor is the advanced exhaust and emission control systems incorporated into the design.

The catalytic converter, a key component, employs chemical reactions to transform harmful exhaust pollutants, such as Hydrocarbons, Carbon Monoxide, and Nitrogen oxides, into less harmful compounds like Water Vapor, Carbon Dioxide, and Nitrogen.

Comparatively, the Concours 14 outshines older models and competitors in emissions control.

The crankcase emission control system and the Kawasaki Clean Air System work in tandem, reducing pollutant levels and contributing to a more eco-friendly riding experience.

Maintenance and Troubleshooting

Users are advised to use only unleaded gasoline to prevent damage to the catalytic converter, which is specifically designed for unleaded fuel.

Additionally, caution is urged against operating the motorcycle if the engine misfires, as this can compromise the effectiveness of the converter.

The crankcase emission control system, a marvel in itself, routes vapors back into the engine for combustion, eliminating their release into the atmosphere.

Regular inspection and maintenance of the Air Suction Valves, responsible for regulating airflow into the exhaust port, are essential for stable idling and performance.

Air Cleaner Maintenance is equally vital, akin to providing the engine with a clean respiratory system.

Timely replacement, especially in challenging conditions, is emphasized, with Kawasaki recommending the use of the designated air cleaner element (part number 11013-0014) to ensure engine longevity and sustained performance.

Discontinuation in Europe

Kawasaki has decided to discontinue the sale of Concours 14 in Europe as it no longer meets the stringent emission standards of Europe.

Compliance with higher emission standards would necessitate significant engine modifications.

The European market, known for its stringent regulatory environment, poses challenges for motorcycle manufacturers seeking to adhere to increasingly demanding emission standards.

In response to this, Kawasaki has chosen to steer European sport touring customers towards the Kawasaki H2, a more aggressive and pricier alternative that aligns with the evolving regulatory landscape.

The decision to redirect customers to the Kawasaki H2 suggests a strategic move to balance compliance with emissions regulations and meet the preferences of European riders.
