Evolution
Rocket engine, a type of IC engine, invented by the Chinese, Mongols and Arabs in 13th century. IC engines of various forms using gun powder or gas fuels invented by Europeans in 17th century.
IC engines in principle similar to modern piston engines invented in 19th century.
Otto four stroke gas cycle
Modern IC engines Gas turbines Jet engines Rotary engines (e.g., Wankel engine) Piston engines
Powering almost all road transport Two stroke and four stroke Gasoline, diesel, gas fuels Naturally aspirated and pressure charged

Tailpipe Emissions control – Motivation IC engines emit noxious gases, namely HC, CO and Nox, and particulates. They lead to local air quality issues like photochemical smog. Governments set regulations to limit these emissions.
HC+NOx
PAN + Ozone
PAN: Peroxy Acetyl Nitrates
Smog Formation
China has amongst the worst air quality in the world already Air quality is the #1 topic of social concern discussed on social media website in china China already has 5 mega cities (> 10 million) and a number of other urban
conglomerates with populations in the 10’s of million

Historical Behaviour The majority of Chinese automotive regulations are heavily based on either US or EU regulations with a time lag of 4 ~8 years There has been relatively minor modifications to adapt to local circumstances “Tactical” implimentation of more stringent regulations (pull ahead) adopted for cities to (try to) address air quality issues More recent behaviour 2020 fuel economy regulation is closer to Japanese model but with multiple modifiers proposed to incentivise technology directions the government wishes the market to follow WLTC is not well received – change is moving away from Chinese market conditions not towards – unlikely to be adopted The focus is very much on fuel economy, not CO2 to address national issues rather than global ones Process is somewhat “fuzzy” with decision making path difficult to follow Incentives for “New Energy” vehicles (PHEV & EV) No incentives for Diesel and unlikely to be widely adopted due to fuel availability and air quality concerns

Chinese fuel economy regulations vs other major markets
•Chinese 2020 fuel economy target is equal to EU goal at around 2017 •It is going to need to be achieved without significant diesel content •By 2025 ~ 2030 it is easy to imagine china will have the same or tougher target as EU

Tailpipe emission standards
Tailpipe emission standard have very closely match EU standards The time-lag from the EU has been around 5 years generally but EU5 is delayed The mega-cities do not wait for the national standard, Beijing implimented C5 in 2013 EU6 is unlikely nationally till mid-2020’s but likely in mega-cities before 2020
The different approach for national regulation and mega-cities illustrates the different in the “3rd world” parts of china (government want to avoid economic burden) and the “1st world” mega-cities with severe air quality issues

Powertrain control complexity
•The technology which has enabled this growth in engine complexity is software (and supporting hardware & CPU’s)
•This complexity is growing at a constant logarithmic rate
![Page 36: The challenges facing OEM’s in the Chinese Market · PDF fileThe challenges facing OEM’s in ... IC engines of various forms using gun powder or gas fuels invented by Europeans](https://reader033.vdocuments.mx/reader033/viewer/2022051523/5a72f1527f8b9ac0538e34a0/html5/thumbnails/36.jpg)
• Joint engine development and manufacture has become fairly common. • Traditionally this has been done to “fill gaps” in OEMs range (niche
engines) but increasingly it is expanding
OEM Strategies to manage Engine Complexity #1 1) Joint developments 2) Example #1 Ford aligned with PSA to develop
diesel engines Example #2 Mercedes and Renault will jointly
develop small gasoline engines together Example #3 BMW and PSA jointly developed
the the 1.6l Prince engine for Mini and PSA
![Page 37: The challenges facing OEM’s in the Chinese Market · PDF fileThe challenges facing OEM’s in ... IC engines of various forms using gun powder or gas fuels invented by Europeans](https://reader033.vdocuments.mx/reader033/viewer/2022051523/5a72f1527f8b9ac0538e34a0/html5/thumbnails/37.jpg)
2) Standardisation of parts BMW will have all of its engines sharing a and systems single cylinder of components - 3 cylinder 1.5litre - 4 cylinder 2.0litre - 6 cylinder 3.0 litre - 8 cylinder 4.0 litre - 12 cylinder 6.0 litre Each engine has a common combustion system
and engine layout
By standardising parts dramatically reduces the number of engineers needed to design, develop, validation and calibrate it’s engines

Unique / key challenges of different major markets
Europe -High speed driving and tendancy to use higher engine RPM -CO2 reduction & EU6 emission regulations (GDI & diesel)
USA -Diagnostic regulations -Tough tailpipe emissions with heavy vehicles
China - Road conditions - Highly variable fuel quality -In-experienced drivers (often never owned a car before) -Low driving speeds and a high tendancy to “lug” in high gears -Immature & variable by region infra-structure for maintainance
• Global engines need to be designed to meet all requirements •For high volume OEM, there is an opportunity for regional variation to tailor
designs to specific markets

Chinese OEM - Catching up 1970’s 1980’s 1990’s 2000’s 2010’s
Having been 10~15 years behind global standards, chinese OEM are “rushing” to catch up – they are already 5~10 years behind and will continue
to quickly catch up

Summary
The chinese market has evolved very rapidly
It is likely to continue to evolve quickly and may not converge with EU and USA
In the past the emissions regulations and the customer expectations were stable and lagged Europe by 5 ~10 years making it “easy” to sell “old” product into the market
The market is now the largest in the world and growing fast (by mature market standards) so it warrants “bespoke” solutions
To be competitive, OEM need global strategies that support the needs of china equally with all other major markets
Good tools & processes backing up a good strategy are needed for success

• Mercedes announced in Nov 2013 that it will combine the manufacturing of it’s 4 & 6 cylinder engines, both gasoline and diesel into one combined flexible line in China
• The 6 cylinder changing from V to Inline • Andreas Renschler explained as follows :
4cyl gasoline 4cyl diesel
6cyl gasoline 6cyl diesel
1 Flexible line for Agile manufacturing
Andreas Renschler VP – Purchasing & Production
“we are producing the four- and six-cylinder versions of diesel and gasoline engines on separate lines so far, we will be able to manufacture all four variations of the next generation on one line”
“Good products are not enough for success, the key is balancing complexity and costs”
“Product diversity is also rising and detailed sales planning is becoming more and more difficult”
“Inflexible production is increasingly turning into Russian roulette”
