De pe la min 30 e concluzia

Din nou amandoi aveti dreptate , dar realist vorbind cati merg cu 200 si opresc "instant" in benzinarie ? Cum am zis vazut pe EGT , daca iau piciorul din acceleratie temperaturile scad , la fel si in relanti . Dar din nou nu strica sa astepti cateva secunde .

Ideal e din nou sa cautam in manual, asa aiurea am cautat ce e drept si am gasit pt 330e , acum daca vrem sa mergem sa despicam firul in 4-5-10, la un motor "normal" nu e bun acest start/stop pe de alta parte la modele vechi clar nu exista , dar din ce tin minte BMW se lauda ca sistemul lor e "optimizat" , acum cat cum strica nu stiu daca poate cineva sa cuantifice .Daca il lasam oprit nu se strica nimic, pornit sa zicem ca avem o sansa foarte mica ( parerea mea) sa se strice ceva . tot de la "sfantul AI" Core Mechanical Components Reinforced Starter Motor: Unlike standard starters, these are built with heavy-duty bearings, stronger planetary gears, and enhanced engagement mechanisms to withstand up to 10 times more start cycles. AGM (Absorbent Glass Mat) Battery: Standard lead-acid batteries cannot handle frequent high-current discharges. BMW uses high-capacity AGM batteries that support deeper cycling and faster recharging. Intelligent Alternator: Often part of BMW's "Brake Energy Regeneration" system, the alternator primarily charges the battery during deceleration to reduce engine load. Electric Water & Oil Pumps: Certain models use electric pumps to maintain coolant and oil circulation while the engine is off, preventing heat soak and ensuring immediate lubrication upon restart. The BMW B58 engine's crankshaft and rod bearings feature a special Irok/Irox coating specifically designed to mitigate the increased wear caused by the engine's auto start-stop system. Impact of Auto Start-Stop The auto start-stop feature, while designed to improve fuel efficiency and lower emissions, poses a potential long-term wear issue for engine bearings due to momentary lack of oil pressure during restarts. Loss of Oil Pressure: When the engine shuts off, the oil pressure drops, and the lubricating film on the bearing surfaces can thin out. During the subsequent restart, there is a brief period with low oil pressure before the system fully pressurizes. Increased Friction: This momentary lack of pressurized oil allows microscopic metal surfaces on the crankshaft and bearings to contact, leading to increased friction and wear over time, especially with frequent city driving stop-and-go cycles. Special Bearing Coating: To address this, BMW uses specific bearings with an Irox polymer coating (a black coating containing a carbon-based material) on the highly stressed upper half of the rod bearings. This coating helps reduce friction and premature wear during the critical seconds of a "dry" restart.

In principiu aveti amandoi dreptate, daca masina e condusa agresiv si bonus afara sunt 40 grade ai sanse sa bulesti ceva pe acolo, daca se merge normal , nu ar trebui sa fie probleme. Astea fiind spuse la Patrol aveam ceas EGT dupa care ma ghidam , ca si "experienta" pot spune ca cel putin pe partea de EGT in 1 min de stat pe loc temperatura scadea sa zicem de la 600 grade la 400 grade , in general cand stiam ca mai am un pic si opresc mergeam mai lejer .

Din manual
-
in teorie macar, la rece , la relanti esti undeva la presiunea minima de ulei , ai ulei gros turatie mica, ma rog asta e teoria la masinile moderne nu stiu cat de mult se mai aplica. Pe de alta parte plecam de la premiza ca ai dai talpa si ICE ala sare brusc in 4-5k ture... In nici un manual auto citit de mine nu se recomanda sa stai pe loc , stiu ca se zicea ceva de genul sa pleci si sa mergi "moderat" dar ma rog din nou ce am citit eu sunt manuale vechi nu stiu ce zice la astea mai noi
-
habar nu am de aia am intrebat, ma rog mai simplu vezi cu o diagnoza, dar daca incalzesti antigel prin ricoseu o sa incalzesti un pic si uleiul
-
Cred ca intrebarea de 1 mil de puncte este- pleci dimineata ca azi -10 grade, odata termicul pleaca? Daca nu pleaca se poate verifica dupa 5 min, daca furtunurile de apa sunt calde/caldute? Sau pus mana bloc, sau o conducta de ulei ? Nu mai stiu pe unde am citit ca Ford a modificat pt Kuga sistemul astfel incat sa "incalzeasca" motorul pana ce e pornit ? edit - am intrebat pe sfantul AI si zice A BMW plug-in hybrid preheats its internal combustion engine as a normal part of its intelligent operation to ensure optimal performance, efficiency, and longevity, especially in cold conditions. The vehicle's system manages this automatically to prepare the engine for when it needs to provide power. How Preheating Works Thermal Management System: The hybrid system is designed with a sophisticated thermal management system that circulates coolant through both the hybrid components and the combustion engine. This helps bring the engine's oil and components to an optimal operating temperature efficiently. Ensuring Full Power Availability: The engine is warmed up in advance so that it can safely provide full power the moment the driver demands it (e.g., during hard acceleration or when the battery is depleted). This prevents putting stress on a cold engine. Optimizing Efficiency: By preheating, the system ensures the engine operates at peak efficiency from the moment it is engaged for propulsion, which helps maximize fuel economy and reduce emissions. Cabin and Battery Preconditioning: In parallel with the engine, the vehicle can also precondition the cabin and the high-voltage battery using electric power, ideally while plugged in, to improve range and comfort before a journey.

Mergeti cu ambele, personal mi-a placut mult cum mergea in mod electric, nu zic ca modelul electric e mai ieftin . Dar pana la urma conteaza mult si daca face drumuri lungi, sau daca poate incarca la munca, alternativ poti instala o statie de incarcare.
-
A e bloc "nou" si parcarea e a ta inteleg ,nu inchiriata de la primarie, atunci rezolvi cu asociatia de proprietari .
-
Nu cred ca poti sa pui asa o statie cum vrei tu , cum a zis trebuie proiect, probabil sunt ceva normative ce te obliga la anumite lucruri. Daca faci prin firma as zice ca cei 2000 eur sunt cost minim. Asa daca luam ca faci cu "Dorel" posibil sa ajungi la 1000-1500 eur .Intrebarea e sa zicem ca o montezi, ce faci dupa? Pui acolo parcare rezervata sau cum ?

In principiu daca mergi zilnici i-ati sa ai "in stoc" asa - PCV , si vas expansiune eventual si radiator. Mergand zilnic o sa inceapa din nou ciclurile de incalzire/racire si daca piesele de mai sus sunt originale as zice ca sunt sanse mari sa cedeze plasticul .PS : daca mergi pe vremea asta evita sa faci drumuri scurte adica mergi macar 10 km sa se incalzeasca cat de cat motorul .

Ciudat ce spui, inseamna ca nu e in 4x4 "permanent"(precum Subaru de exemplu) ci mai degraba FWD si in caz de nevoie intra spatele ,in cazul tau probabil ca intrand tare sistemul a reactionat dar dupa ce masina alunecase deja . Din punctul meu de vedere sistemul folosit pe E30 e cel mai "avansat" si citez de pe wiki "These cars use centre and rear differentials with viscous couplings to vary the torque split between wheels. The centre differential has a default front:rear torque split of 37:63, due to the planetary gear.[5] Up to 80% of the torque can be transferred to the tripping axle, using the increasing shear force of the silicone fluid in the viscous coupling (due to the slotted/grooved plates inside the unit) as wheel slip causes one axle to spin faster than the other. The same principle applies to the rear differential varying the torque split between the rear wheels. The front differential has no locking function." Un video celebru unde se poate vedea cum merge.

Ce poti face cu fratele mare al lui asta micu după ce îl modifici

Sunt ceva Lexus cu 3,3 acolo e "lovitura" mai serioasă.
