Jan 7th, 2016 Dakar Rally Stage 5 Race Info & Discussion

Join in and discuss all the action from Stage 5 of the 2016 Dakar Rally. Robby Gordon finished 10th in Stage 4, and his teammate, Sheldon Creed, finished 26th, after receiving a 10 minute penalty for speeding. The special section of Stage 5 is 327km. Robby Gordon start time: 9:21am/et, Sheldon Creed start time: 9:47am/et.

STAGE 5 TRACKING


STAGE 5: SAN SALVADOR DE JUJUY > UYUNI

Connection 315km | Special Stage 327km | Total 642km

COURSE OVERVIEW

All round vigilance is required for this second part of the marathon stage: in addition to managing mechanics, particularly the tyres, all the drivers will have to pay attention to their own bodies’ reactions. Entry into Bolivia is also marked by an abrupt increase in altitude, rising to 4,600m –the higher point in Dakar’s story- during the day’s special section. Technically, it is also in this stage that the rally steps up a gear, with the first off-piste sections as well as some navigational gems which might be a headache for some navigators…


The GREEN section of the route is the connection , the RED is the Special Section of the stage.

Per Dakar site: Rain forecast
For yet another very difficult day of racing, the weather forecasts are not predicting any improvement with regard to the amount of precipitation. In fact, heavy rain is expected, which could severely complicate the task for the competitors still in the race. In light of the weather, the special around rather than through the Uyuni salt pans, missed by some, will most probably be appreciated by all

They don't show him of course but you here his name being yelled. https://m.facebook.com/story.php?story_fbid=1042947265764580&id...

Excessive penalties on Robby Gordon, blocking Robby Gordon and peugeot cheating with their engines - That would be Dakargate.

Has to be proved, that is the problem

This seems to be more of a chess game than a race, RG/TS is playing the game. it's not just on the track but in the media as well. I think he is playing his hand well.

2.7 V6 HDI

USED IN MANY VEHICLES

The combination of a modern turbo diesel engine and the highly advanced aluminium body of the XJ range delivers an exceptional package of performance, dynamics, refinement and economy. All the advantages of modern diesel engines - fuel efficiency, relaxed motoring and impressive power delivery - are only amplified by linking them to a super-strong and lightweight chassis, like that of the XJ.

Launched in Jaguar's mid-range S-TYPE saloon in 2004, Jaguar's state-of-the-art twin-turbo V6 Diesel sets new standards in refinement and performance. The highly efficient 24-valve engine features advanced technologies, including the latest generation high-pressure, common rail, direct-injection fuel system and a lightweight, compacted graphite iron (CGI) cylinder block.

The outstanding strength and durability of CGI means that less material is needed than for a conventional cast iron block, ensuring reduced engine weight and length. In fact, the new diesel engine is the lightest unit of its type, at just 202kg. This significantly contributes to the excellent power-to-weight ratio and fuel economy.

Other features at the heart of the engine provide the capability to deliver high performance and excellent durability. Cast aluminium pistons incorporate ‘double wave-gallery' cooling. In this process, oil is sprayed precisely onto the inside of the pistons from jets in the block. The oil then flows through two internal wave-shaped channels to help cool each piston crown. This arrangement also has the indirect benefit of reducing piston ‘slap' noise.

Management of the engine's noise characteristics has focused particularly on injector tick and combustion noise, which is controlled through the use of next-generation common rail technology, including ‘multiple-point' injection and closed-loop injection control, which ensure that the combustion is smooth under all operating conditions.

The fuel quantity provided by each injector is controlled by a Piezo actuator, which enables highly accurate fuel metering of up to five injections per cycle. These features provide an extremely fine spray of diesel fuel, which ensures the most uniform fuel-air mixture possible, resulting in a more complete combustion process. As a result, the diesel engine is able to achieve both high power and the desired emissions capability.

From the outset, the 2.7 twin-turbo Diesel engine was designed to meet future emissions levels. However, further advances in reducing emissions since the launch of the S-TYPE twin-turbo Diesel have been made through changes to the fuel injection system, utilising higher injection pressures and different injector spray patterns. The calibration of the electronically actuated turbochargers, the exhaust gas recirculation system and port deactivation have also been revised. With the addition of a Catalysed Diesel Particulate Filter (CDPF), the advanced design of the V6 engine ensures it exceeds Euro Stage IV emissions requirements.

Aiding both performance and emissions is a forced induction system, comprising twin-turbochargers with state-of-the-art electronic actuation. Traditionally, turbochargers are vacuum actuated, but this new form of rotary electric actuator gives a higher degree of control, providing benefits in the areas of emissions and transient engine performance, as well as in balancing performance and emissions between the two cylinder banks. The turbochargers are a low inertia type for quick, responsive, power delivery.

The high-grade aluminium alloy cylinder heads are equipped with four valves per cylinder and double overhead camshafts. This combination provides optimum induction and exhaust actuation, with attendant benefits in performance and emissions. The cylinder head design includes a port deactivation system and pistons with toroidal combustion chambers, producing a highly efficient combustion capability. A low - by diesel standards - compression ratio of 17.3:1 contributes to improved emissions quality, quieter combustion and compatibility with the engine's unique forced induction system. In a diesel engine, reduced compression means less heat build-up in the piston bowl and more efficient fuel burn, resulting in lower levels of pollutants.

A revised secondary bulkhead structure has been introduced to the engine compartment of all XJ models - both diesel and petrol - to reduce interior noise levels by up to 5 decibels. The result is the most refined vehicle in its class for interior comfort.

The XJ Diesel is also the quietest vehicle in its class for exterior noise, with the noise level measured by the Vehicle Certification Agency being 7 decibels (A) lower than the EU legal limit for diesel vehicles. In order to achieve this, the exterior noise package has been significantly enhanced.

The XJ 2.7 litre twin-turbo Diesel is best-in-class for isolation from engine idle vibration. This is achieved with active engine mounts, which are introduced on all 2006MY XJ Diesels and are an industry first. The engine mounts were designed and developed in conjunction with Avon Automotive. Diesel engines generate much greater levels of vibration than their petrol equivalents, which is why the mounts are being fitted to the XJ Diesel variants. Active mounts use an electronic control system and a powered mechanism to cancel an additional 90 percent of this engine vibration at idle.

Huh wow that's a lot of words man

Good demonstration on the air restrictor Mike...

Here is the NBC videos for anyone that missed Robby's comments about his frustrations right now.

Thanks, not many people have a pair of 39mm big bell Lectron's laying in a box in the shop.I modified this pair 30 years ago.Damn

thx
