The bike Power Trio: PS, BHP, and kW
Three units frequently emerge when discussing motorcycle engine power: PS, BHP, and kW. These units have a rich history, with each one evolving to meet the automotive industry’s changing needs. Understanding these units, their origins, and their significance will make you feel more informed and knowledgeable about motorcycles.
PS (Pferdestärke)
- PS stands for Pferdestärke, German for “horse strength” or metric horsepower.
- It is a metric power unit equivalent to approximately 98.6% of one mechanical horsepower (HP).
- PS is commonly used in European countries to denote the power output of engines and is often seen in vehicles imported from European manufacturers.
BHP (Brake Horsepower)
- BHP is a measure of an engine’s horsepower before the loss of power caused by the gearbox, alternator, water pump, and other auxiliary components.
- It represents the power output of an engine measured at the crankshaft.
- BHP is considered a more realistic measure of an engine’s power as it accounts for frictional losses within the engine.
- It is commonly used in the UK and the US and has been widely adopted in the Indian motorcycle market.
kW (Kilowatts)
- A kilowatt (kW) is a metric power unit equivalent to 1,000 watts. It is part of the International System of Units (SI).
- It is increasingly used in the context of electric motorcycles and vehicles, providing a direct measure of electrical power.
- In the European Union, kW has been the officially recognized measurement of engine power since 1972. However, manufacturers often quote both kW and PS.
Conversion between motorcycle engine power units
Understanding how to convert between these power units is crucial for comparing motorcycles across different regions and measurement systems. Here are the key conversion formulas:
- PS to kW: 1 PS ≈ 0.7355 kW
- BHP to kW: 1 BHP ≈ 0.746 kW
- PS to BHP: 1 PS ≈ 0.986 BHP
These conversions are essential for automotive enthusiasts, engineers, and anyone involved in the motorcycle industry, especially when dealing with international specifications where different units might be used.
Testing & reporting of motorcycle engine power in India
Testing and reporting of motorcycle engine power output involve several key organizations in India, and they are.
1. Ministry of Road Transport and Highways (MoRTH)
This is India’s primary body responsible for setting emissions and efficiency standards. It plays a crucial role in the regulatory framework for vehicle testing, including motorcycles.
2. Automotive Research Association of India (ARAI)
ARAI is a key agency involved in the certification and standardization of automotive vehicles in India. It provides services related to vehicle type certification, testing, and calibration, essential for ensuring compliance with regulatory standards. ARAI conducts tests to ensure that vehicles meet the required standards for roadworthiness and emissions.
3. International Centre for Automotive Technology (ICAT)
Alongside ARAI, ICAT is another significant agency contributing to India’s automotive testing and certification process. It is involved in setting and enforcing standards for vehicle testing.
4. Bureau of Indian Standards (BIS)
BIS is India’s national standards development organization. It creates and maintains standards for industries, including the automotive sector, including those related to motorcycle engine testing.
Testing Methods and Standards
The testing of motorcycle engine power output in India involves several standardized methods and procedures:
1. Dynamometer Testing
This is the most common method for testing engine power output. A dynamometer applies a load to the engine and measures the resulting torque and power output at varying speeds. Different types of dynamometers are used depending on the specific requirements of the test, and they are essential for obtaining accurate measurements of engine performance.
2. Automotive Industry Standards (AIS-137)
The AIS-137 is a comprehensive set of standards that prescribes test methods, testing equipment, and related procedures for type approval and conformity of production testing of vehicles, including motorcycles. This standard is crucial for ensuring that motorcycles meet the required performance and safety criteria before being approved for market sale.
3. Indian Drive Cycles and RDE Program
The Indian Drive Cycles and Real Driving Emissions (RDE) program is part of the vehicle certification procedures, including testing engine performance and emission compliance. These procedures ensure motorcycles meet power output standards and adhere to emission norms.
4. Bharat Stage Emission Standards
While primarily focused on emissions, the Bharat Stage Emission Standards also indirectly influence engine power testing by limiting pollutants, affecting engine tuning and performance. These standards were instituted by the Government of India and are crucial for regulating the output of air pollutants from motorcycles.
FAQ related to PS/Bhp/KW motorcycle engine power units in India
1. Why do some Indian bike manufacturers use PS while others use Bhp?
For instance, European brands like BMW and Ducati often use PS in their specifications. In contrast, domestic brands like Royal Enfield and Bajaj use BHP. This inconsistency can lead to confusion among consumers when comparing different models.
2. Does higher PS/Bhp/KW always mean better bike performance?
Higher power outputs generally correlate with better performance, but that’s not always the case. Factors such as torque distribution, which determines the motorcycle’s ‘pulling power,’ engine tuning and overall motorcycle design, play crucial roles in real-world performance. Understanding these factors will help you make more informed decisions when choosing a motorcycle.
3. How do power units affect motorcycle insurance premiums in India?
Cubic capacity (CC) is the primary factor in insurance premiums, and power output (measured in PS, Bhp, or KW) can influence risk assessment. Generally, more powerful bikes are associated with higher risks and potentially more expensive repairs, leading to higher insurance premiums.
4. How do power units impact the pricing of motorcycles in the Indian market?
Higher power outputs typically correlate with higher prices due to increased manufacturing costs and advanced technology. In India, market segmentation is often based on power output, with high-performance bikes priced at a premium compared to entry-level models.
5. What’s the relationship between a motorcycle’s power unit and fuel efficiency?
Larger engines with higher power outputs can consume more fuel, technological advancements have allowed for more efficient engines that can effectively balance power and fuel consumption.
6. Can I directly compare motorcycles with different power units (PS vs Bhp)?
While PS and Bhp are often used interchangeably in marketing materials, they are not identical. The conversion (1 PS ≈ 0.986 BHP) is crucial for accurate comparisons.
